Power factor correc-tion is the switching ofcapacitors in parallelwith inductive linear ornon-linear loads in thenetwork.The decisive factorsin the selection ofpower factor correc-tion are the networkconditions and theload structure.

n Networks conditionsIt is essential to con-sider any harmonic con-tent that is present,both in the low-voltagenetwork and in thehigher-level medium-voltage network.AF ripple control sys-tems that are presentmust also be takeninto account in the se-lection of power factorcorrection.

n Load structureIf the proportion of non-linear loads (e.g. con-verter drives) in thelow-voltage network is≥ 20 % of the preced-ing transformer appar-ent power rating Sr,then 4RF capacitorswith reactors shouldbe chosen.

nBranch

A branch is the capacitor ratingswitched from a controller out-put.

nTuned filter circuits

A tuned filter circuit comprisesa series connection of a capaci-tor and a reactor (filter circuit re-actor), which are matched insuch a manner that the reso-nant frequency fR of the seriesoscillating circuit precisely cor-responds to a harmonic fre-quency.Since the impedance of seriesoscillating circuits is extremelylow (practically zero) at reso-nant frequency, the relevantharmonic current is “filtered”.Tuned filter circuits are capaci-tive at the fundamental fre-quency and act as phaseshifters, however, they cannotbe controlled by a P.F. control-ler.

nHarmonic filtering

Harmonic currents can causecritical interference in powersystems.With the employment of ca-pacitors with reactors the inter-ference is mitigated or evencompletely removed.The degree of harmonic filter-ing achieved is dependent onthe design and configuration ofthe filter circuit reactors and ca-pacitors.The reactor/capacitor ratio p isa characteristic of the degreeof harmonic filtering.The degree of harmonic filter-ing increases as p decreases.

nResponse time

The response time of the con-troller is the time period forwhich a signal (reactive powerrequirement) must be appliedin order to produce a switchingcommand from the controller.

nC/k value

The C/k value is the responsevalue of a P.F. controller.It is given by the capacitor rat-ing C of the first branch circuitand the C.T. ratio k.

With most controllers this re-sponse value must be calcu-lated and set on the controllerduring set-up.The SIMEAS C controllers de-termine the C/k value automat-ically and no controller settingsneed to be carried out by theperson setting up the control-ler (self-adaptation to C/kvalue).

n Inrush current spikes,precharging resistors

Switching a single capacitor onto the network does not causeany problems, because the cur-rent is limited by the induc-tance of the upstream trans-former and the cables.The switching of capacitorbanks (switching one capacitorin parallel to those already in cir-cuit) is substantially more criti-cal, because here the inrushcurrent is only limited by thelow inductance of the connect-ing cables and capacitors.This problem can be overcomeby using special capacitor con-tactors with precharging resis-tors. Capacitor contactors incor-porate resistors which areswitched in circuit by makecontacts before the main con-tacts are closed. The currentspike is thereby damped to ap-prox. 10 % of its undampedvalue.

nDischarge device,discharge time

Discharge devices are used todischarge capacitors after dis-connection from the network.This means that they must beable to dissipate the energy

stored in the capacitor within afew seconds. Suitable dis-charge devices are resistorsand reactors.Due to their high AC induct-ance, discharge reactors pro-duce very low losses at sys-tem frequency.

EN 60831-1, section 4 statesthat any capacitor bank or bat-tery must be discharged withinthree minutes from its initialpeak voltage to 75 V or less.However, capacitors alwayshave to be discharged to 10%of the rated voltage before be-ing switched in again. In auto-matically controlled P.F.C. cir-cuits the capacitor must bedischarged within a few sec-onds, because the controllercan, due to a changing load, is-sue a switch-in signal for thesame capacitor after only ashort delay, switching in the ca-pacitor which has been justswitched off. The dischargetime in P.F. correction unitsmust always therefore be lessthan the controller responsetime .

n Impedance factor αFor a customer’s system thisis the ratio of the audio fre-quency impedance to the net-work frequency impedance. Incontrast to the blocking factor,the impedance factor takesinto account the influence ofthe ratings of the networktransformer and the P.F. cor-rection system. The ratio oftransformer power rating tothe P.F. correction power rat-ing mainly determines the inter-ference effects on the audio-frequency ripple controlsignals. If the P.F. correctionpower rating is low comparedto the transformer power rat-ing, then impermissible inter-ference on the audio-fre-quency ripple control signalsshould not be expected.

n Impulse withstand capabi-lity

Capacitors used in automaticpower factor correction unitsand which are therefore sub-ject to frequent switching, re-quire high impulse withstandcapability, because the high in-rush current stresses the ca-pacitor windings as well as theswitching devices (see pre-charging resistors).

nCapacitance stability

Capacitance stability meansconformance to the electricaldata over the whole servicelife of the capacitor. This is es-pecially very important withdetuned and tuned filter cir-cuits.Permanent conformance tothe tuning frequency is onlypossible with filter circuits ifthe loss of capacitance in thecapacitors due to ageing is ex-tremely low.

nPower capacitors

Power capacitors are usuallythree-phase capacitors with ahigh capacitance rating andconform to EN 60831-1,IEC 831-1.They are used exclusively forphase shifting.Power capacitors featuren high capacitance stability

and long service lifen internal protection systemn high pulse withstand capabil-

ity.These characteristics are espe-cially important in reactor con-nected applications.

Linear loads

When connected to a sinusoi-dal system voltage, linear loadsdraw a sinusoidal currentwhich may be phase shiftedwith respect to the voltage.Examples of linear loads are:Three-phase motors,Capacitors,Filament lamps,Resistor heating.

nMotor capacitors

Motor capacitors are single-phase capacitors and conformto DIN VDE 0560 Part 8.They are generally of low ca-pacitance rating and are de-signed for starting or runningmotors.In contrast to power capacitorsmotor capacitors have:n no protection systemn lower capacitance stability

and a shorter service lifen lower impulse withstand ca-

pability.If required, single-phase motorcapacitors can be connected toform three-phase units.

Definitions

nNon-linear loads

On application of a sinusoidalsystem voltage, non-linearloads draw a non-sinusoidalcurrent from the network.Examples of non-linear loadsare:n Variable-speed drives,n Frequency converters,n Uninterruptible power sup-

plies,n Dimmers, television sets,n Devices with saturated mag-

netic circuits,n Fluorescent lamps,n Arc furnaces, welding equip-

mentn Semiconductors (diodes

and thyristors).

nHarmonics

Non-linear loads draw a non-lin-ear current from the network.This non-sinusoidal current canbe broken down using Fourieranalysis into a fundamentalwave with frequency f1 and su-perimposed harmonics withfrequencies .

nOrdinal number νThe ordinal number ν is a pa-rameter describing the harmon-ics. It represents the ratio ofthe harmonic frequency to thesystem frequency. ν = 5 indi-cates the 5th harmonic withthe frequency fν = ν ⋅f1.At f1 = 50 Hz, f5 = 250 Hz.At f1 = 60 Hz, f5 = 300 Hz.The amplitude of the harmoniccurrents decreases with the in-crease in the ordinal number re-ferred to the fundamentalwave.

e.g.:

nStep function ratio

The step function ratio is the ra-tio of the branch ratings. Fiveequal branches give a stepfunction ratio of 1:1:1:1:1.With a Siemens P.F. controllerthe step function ratio can beselected almost arbitrarily andcan be simply modified bychanging the ratings of thebranches.

nResonance effect

In compensated AC power sys-tems a special case may occurin which the inductive and ca-pacitive impedances canceleach other. Since with the volt-age applied only a relativelylow ohmic resistance acts tolimit the current, high currentspikes occur which can evencause the tripping of overcur-rent protection devices.

nResonance frequency

At the resonance frequency fRthe reactances XL and XC of aseries oscillating circuit areequal and opposite and thuscancel each other (XL = XC ).Therefore, the impedance ofthe oscillating circuit is practi-cally zero at the resonance fre-quency since only the relativelysmall ohmic component is ac-tive.

nSelf-healing, self cut-off

Dielectric flashovers in the ca-pacitor caused by voltagespikes are isolated by self-heal-ing. The capacitor remains ca-pable of continued operationduring the self-healing process.If in exceptional casesflashovers occur particularly fre-quently, then the ensuing over-pressure activates a mechani-cal protective overpressurecut-off at a predeterminedbreaking point within the ca-pacitor winding, isolating thecapacitor from the network.

nBlocking factor af

This is the ratio of the audio fre-quency impedance ZfT for asystem (e.g. capacitor with AFblocking device or capacitorwith reactors) to the reactanceXC of the capacitor at the sys-tem frequency f1 (e.g.50 Hz).

nNumber of steps

The number of steps is de-fined by the step function ratio.The number of steps is calcu-lated by adding the numbers inthe step function ratio. For ex-ample, for the step function ra-tio 1:1:2:2:3, the number ofsteps would be 9.In order to obtain a sufficientlyaccurate control and also toprevent too frequent switch-ing, a number of steps be-tween 5 and 12 is recom-mended. A large number ofsteps does not result in a sig-nificant improvement of thepower factor.

nAF ripple control systems,AF blocking device

AF ripple control systems feedAF pulses into the publicpower supply system.These pulses are propagatedthroughout the power systemand are received by AF receiv-ers distributed over the powersystem which perform the re-quired switching operations.AF ripple control systems areemployed, for example, for:n Tariff control of private prem-

ises and industrial plants,n Switching of alarm signals,n Switching of lighting installa-

tions.The frequency dependent im-pedance of capacitors installedin the power system can inter-fere with the AF signals.For such applications the ca-pacitors must be equippedwith AF blocking devices in or-der to avoid excessive over-loading of the AF ripple controlsystems.Generally, an AF blocking de-vice is connected upstreamwith the capacitor.In power systems with har-monics either special reactorconnected capacitors or spe-cial AF blocking devices areemployed for AF signal rejec-tion in conjunction with capaci-tors with reactors.

nReactor / capacitor ratio

The reactor / capacitor ratio p[%] reflects the ratio of induc-tive reactance to capacitive re-actance at system frequency.The resonance frequency fR ofthe series resonant filter circuitis indicated indirectly by p.E.g.: p = 7 % fR = 189 Hz

p = 5.67 % fR = 210 Hz

The relationship between pand fR is given by:

E.g. p = 7 %,system frequencyf1 = 50 Hz

nCapacitor with reactors(detuned filter circuit)

A capacitor with reactors is aseries connection of a capaci-tor with a reactor. This re-presents a series oscillating cir-cuit, whose resonancefrequency fR is chosen by de-sign of the reactor so that itlies below the frequency of the5th harmonic (250 Hz at apower frequency of 50 Hz). Asa result the reactor / capacitorsystem is inductive for all har-monic frequencies ≥ 250 Hzand dangerous resonances be-tween the capacitor andpower system inductances(e.g. transformers) will not oc-cur.Capacitors with reactors areswitched by power factor con-trollers.

nSIPCON T

SIPCON = Siemens PowerConditioning.This includes components andcomplete systems which,when connected to the powersystem, produce substantialimprovements in the powersystem quality.SIPCON T (Traditional Compen-sation) provides a decisive con-tribution to power systemquality using power factor cor-rection and harmonic filtering.Further information on SIP-CON see Catalog SR 10.5,1998.

Description

n Field of application

4RB5 power capacitors areused in fixed compensationunits and in power factor cor-rection units.Capacitors for power factor cor-rection without reactors shouldonly be used for power sys-tems where the converter loadis less than 20 % of the totalload. Capacitors in the ISO pro-tective housing can be con-nected directly at the load asfixed compensation units.Capacitors for power factor cor-rection with reactors should beused with reactors for powersystems where the converterload is greater than 20 %.

nDesign

The metal coatings of 4RB5MKK power capacitors are va-pour deposited on apolypropylene foil. The foil actsas the substrate as well as thedielectric.The capacitors are filled with aprotective gas and are there-fore dry-type capacitors.The capacitors are self-healing.They are protected against im-permissibly high overloads bymeans of an internal overpres-sure cut-off.When this protection trips, thecapacitor housing extends byabout 10 mm in the directionof the terminals.An appropriate safety distanceto neighbouring componentsor housing parts should be al-low-ed.

4RY Small Power Factor Correction Units without Reactorswith or without built-in AF blocking device

Description


4RY small power factor correc-tion units are used for central-ized power factor correction ofinductive loads in power sys-tems without or with a con-verter load less than 20 % ofthe total load.

nDesign of the various 4RYsmall power factor correc-tion units

4RY16 and 4RY19/29 smallpower factor correction unitsare mounted on base plateswith dry power capacitors,with capacitor contactors and adischarge device.The base plate is built into asheet-steel or moulded-plastichousing.4RY36 and 4RY39/49 smallpower factor correction unitsare constructionally identicaland they also contain an AFblocking device.The power factor correctionunit and AF blocking device arebuilt into a suitable sheet-steelor moulded-plastic housing.

nConnection

Connection to the power sys-tem is made using cables.Each power factor correctionunit contains appropriate cableterminals. The connection ofthe current transformer leadsis made to the transformer ter-minals.

nOperating principle

The power factor controllermeasures the reactive powerpresent and, when deviationsfrom the setpoint occur, it is-sues switching commands tocontactors. These switch ca-pacitor branches in or out de-pending on the requirements.The capacitors are dischargedwithin a few seconds afterswitching off.For 4RY small power factor cor-rection units the controller BLRCC is used, see page 13/1.

Important note:

Power factor correction unitswith AF blocking circuits areonly designed for power sys-tems with low harmonic con-tent.The harmonic voltages u5 andu7 must not exceed 3 %, re-spectively 2 %, because other-wise resonances within the AFblocking circuits will cause over-loads.

As an alternative to AF blocking,power factor correction unitswith reactors (7 % or 14 %)can be used. See selection dia-gram on page 1/4 for the selec-tion of power factor correctionunits with regard to AF ripplecontrol.

Description


4RY18/28 power factor correction unitswithout reactors and ready for connectionare used in low-voltage power systemswith low harmonic content, correspondingto a proportion of non-linear load less than20 % of the upstream transformer ratedpower.Similarly, the harmonic content of thehigher level medium-voltage networkshould be taken into account because ca-pacitors without reactors can, related tothe medium-voltage network, form a se-ries resonant circuit with the networktransformer.If its resonant frequency is located in thevicinity of a low frequency harmonic, net-work disturbances can be created undersome circumstances.4RY18/28 power factor correction unitscan be supplied for almost all systemvoltages occurring throughout the world.

nDesign

The 4RY18/28 units with 75 kvar to 150 kvarare installed on base plates in sheet-steelhousings. The degree of protection for thehousing can be taken from the selectionand ordering data.The 4RY18/28 units greater than 150 kvarare installed with 4RY56 modules, seepage 6/2, in sheet-steel cabinets with ven-tilation slots and natural cooling. The4RY38/48 units are constructionally identi-cal to the 4RY18/28 units, but also containan AF parallel blocking circuit. The degreeof protection can be taken from the selec-tion and ordering data.The SIMEAS C controller, see page 12/2,is installed as the power factor controller.


The power factor controller measures theinductive reactive power present in thenetwork and also the correspondingpower factor. It compares this with theset target cos ϕ and switches capacitorsin or out as required using the contactorsin the capacitor modules. The SIMEAS Ccontroller automatically determines thecapacitor ratings connected to its outputsand immediately switches in the capacitorrating which best corresponds to therequirements. This method optimizes thenumber of switchings.

nConnection

The connection to the power system ismade using cables. Each P.F. correctionunit contains appropriate cable terminals.The connection of the current transformerleads is made using the transformer termi-nals provided.

The power factor correction units from 30 kvarto 200 kvar are constructionally identical to theunits for 230 V 60 Hz; due to the system

frequency of 50 Hz, the rating on the network is 20 % lower.The order numbers are identical and the capacitor contactorsare suitable for 50 Hz or 60 Hz.

Units for the system voltagesAC 415 V 50 Hz, 440 V 60 Hz,480 V 60 Hz, 525 V 50 Hz and690 V 50 Hz are constructionallyidentical to the 400 V units.The order number as shown on page 5/5only changes in the 8th position.

Units for other system voltages areavailable on request.

Important:

If no external control voltage is available, a controltransformer is needed for system voltages from500 V.In this case -Z, A12 or A13 is to be added to theorder number, see page 13/2.

Important note:

Power factor correction units without reactors and with AF blok-king circuits are only designed for power systems with low har-monic content. The harmonic voltages u5 and u7 must not ex-ceed 3 %, respectively 2 %, because otherwise resonanceswithin the AF blocking circuits will cause overloads.As an alternative to AF blocking, power factor correction unitswith reactors (7 % or 14 %) can be used in networks with AFripple control. See selection diagram on page 1/4 for the se-lection of power factor correction units with regard to AF ripplecontrol.

Description


4RY56 capacitor moduleswithout reactors are employedfor forming power factor cor-rection units without reactors.The modules are suitable foruse in low-voltage networkswith a low harmonic content,corresponding to a proportionof non-linear load less than20 % of the upstream trans-former rated power.Similarly, the harmonic con-tent of the higher level me-dium-voltage network shouldbe taken into account becausecapacitors without reactorscan, related to the medium-voltage network, form a seriesresonant circuit with the net-work transformer.If its resonant frequency is lo-cated in the vicinity of a lowfrequency harmonic, networkdisturbances can be createdunder some circumstances.

nDesign

The 4RY56 modules on a gal-vanized sheet-steel chassisare fitted with dry-type 4RB5MKK power capacitors with ca-pacitor contactors and with dis-charge devices for the fast dis-charge of the capacitors(4EJ99 discharge reactors orresistors). For connecting themodules together and for theconnection to the power sys-tem via cable, each 4RY56module has a 60 mm busbaradapter system with copperbars E-Cu 30 x 10 mm mount-ed at the front.

nMounting information

The mounting holes on the4RY56 modules are univer-sally suitable for 20 mm and25 mm pitch.The 25 mm pitch of theSiemens 8MC cabinet serieswith alternative square andround holes with thread en-tries for self-tapping screwsare ideal for mounting mod-ules.The 4RY56 modules are sim-ply suspended on these sup-porting pillars and mountedwith self-tapping screws.See page 5/2 for completeunits formed from 4RY56modules.

The module width for 600mm cabinet width is 580 mm.Normally, the supporting pil-lars included in the cabinet sys-tem can be used.The module width for 800mm cabinet width is 720 mm.This means that the modulescan pass through the cabinetdoor opening without anyproblem, but the mountingpanel width must be takeninto account when selectingthe supporting pillars.If required, supporting pillarsfor certain types of cabinetcan be supplied with the mod-ules on request, see Accesso-ries on page 13/2.

nElectrical connections

On the power side the 4RY56modules are connected to-gether via the busbar systemat the front. The busbars areconstructed such that no extraconnecting lugs are required.One 4RY56 module per sec-tion contains special busbarsections which are suitable foraccepting the connecting ca-bles.The connection of the 4RY56module on the control side tothe power factor controllerand to the control voltage isprovided by control lineswhich should be routed in asuitable manner (e.g. cableducts).

Description


4RF1/2 power factor correc-tion units with reactors aresupplied ready for connectionfor use in low-voltage powersystems with high harmoniccontent corresponding to aproportion of non-linear loadgreater than 20 % of the up-stream transformer ratedpower.The tuned frequencies of thecompensation system with re-actors are below the 5th har-monic.So capacitors with reactors al-ways have an inductive im-pedance with regard to har-monics.Resonance problems, whichcan occur with compensationsystems without reactors inpower systems containing har-monics, are improbable in thiscase.Apart from capacitive reactivepower, power factor correc-tion units with reactors alsoprovide filtering of low fre-quency current harmonics.The lower the level of reactor/capacitor ratio p in %, thegreater is the filtering of the5th and 7th current harmon-ics. If present however, AF rip-plefrequency levels less than350 Hz are also reduced.In order to prevent impermissi-ble interferences, the selec-tion of the power factor correc-tion unit with reactors shouldbe carried out according topage 1/4 taking into considera-tion existing audio frequen-cies. The selection tables alsocontain information about ap-plication in power systemswith AF ripple control.

nDesign

The 4RF1/2 units with ratingsup to 75 kvar are mounted onbase plates in sheet-steelhousings. The degree of pro-tection for the housings canbe taken from the selectionand ordering data.The 4RF1/2 units with ratingsgreater than 75 kvar are form-ed using 4RF5 modules (seepage 9/2) in sheet-steel cabi-nets with ventilation slots andnatural cooling. For 250 kvarper 600 mm section and 400kvar per 800 mm section anadditional fan module is in-stalled. The degree of protec-tion for the housings can betaken from the selection andorder-ing data.The SIMEAS C controller is in-stalled as the power factorcontroller, see page 12/2.


The power factor controllermeasures the inductive reac-tive power present in the net-work and also the correspond-ing power factor. It comparesthis with the set target cos ϕand switches capacitors in orout as required using the con-tactors in the capacitormodules.The SIMEAS C controller auto-matically determines the ca-pacitor ratings connected toits outputs and immediatelyswitches in the capacitor ratingwhich best corresponds to therequirements. This method op-timizes the number of switch-ings.

nConnection

The connection to the powersystem is made using cables.Each P.F. correction unit con-tains appropriate cable termi-nals.The connection of the currenttransformer leads is made us-ing the transformer terminalsprovided.

4RF3 Power Factor Correction Units with SpecialReactor Connected Capacitors, 4RF4 Extension Unitswith AF blocking < 250 Hz and simultaneous high harmonic filtering

Description


4RF3/4 power factor correc-tion units with special reactorconnected capacitors areready for connection and foruse in low-voltage power sys-tems with a high proportion ofharmonics where the non-linear load may be greaterthan 20 % of the upstreamtransformer rated power. Thetuned frequencies of the com-pensation system with reac-tors are below the 5th har-monic. Thus capacitors withreactors always have an induc-tive impedance with regard toharmonics. Resonance prob-lems which can occur withcompensation systemswithout reactors in power sys-tems containing harmonicsare improbable in this case.Apart from capacitive reactivepower, 4RF3/4 power factorcorrection units with reactorsalso provide filtering of low fre-quency current harmonics.Due to the special reactor con-nection, which is either a paral-lel circuit of various reactorsand capacitors or a combina-tion of reactors and capacitorswith an AF parallel blocking de-vice, adequate blocking of AFfrequencies below 250 Hz isobtained despite high filteringof the 5th and 7th harmonics.The selection tables contain in-formation about application inpower systems where AF rip-ple control is in operation.The 4RF3/4 units are availablefrom ratings 200 kvar up-wards, because the requiredhigh harmonic filtering only be-comes relevant from an appro-priate capacitor rating. If the re-quired capacitor rating is lessthan 200 kvar, then 4RF19power factor correction unitswith reactors (14 %) shouldbe selected, see page 7/10.

nDesign

The 4RF3/4 units are built upfrom 4RF5 modules (see page9/2) in a sheet-steel cabinetwith ventilation slots and natu-ral cooling. A fan module isneeded from 400 kvar per sec-tion. The degree of protectionfor the housings can be takenfrom the selection tables.The SIMEAS C controller isbuilt in as the power factorcontroller, see page 12/2.When reactor connected incombination (parallel circuit ofvarious capacitors with reac-tors), the 4RF34/44 units canprovide power ratings up to400 kvar per section.Depending on the audio fre-quency present, the 4RF36/46units have 7 % or 8 % reactor/capacitor ratio with a built-inAF parallel blocking device.Power ratings up to 300 kvarper section are possible.


The power factor controllermeasures the inductive reac-tive power present in the net-work and also the corre-sponding power factor. Itcompares this with the set tar-get power factor and switchescapacitors in or out as re-quired using the contactors inthe capacitor modules.The SIMEAS C controller auto-matically determines the ca-pacitor ratings connected toits outputs and immediatelyswitches in the capacitor ratingwhich best corresponds to therequirements. This method op-timizes the number of switch-ings.

nConnection

The connection to the powersystem is made using cables.Each P.F.C. unit contains ap-propriate cable terminals.The connection of the currenttransformer leads is made us-ing the transformer terminalsprovided.

Description


4RF5.. capacitor moduleswith reactors are employedfor forming power factorcorrection units with reac-tors. The modules are suit-able for use in low-voltagepower systems with a highharmonic content, corre-sponding to a proportion ofnon-linear load > 20 % ofthe upstream transformerrated power.

nDesign

The 4RF5.. modules on agalvanized sheet-steel chas-sis are fitted with dry-type4RB5 MKK power capaci-tors with capacitor contac-tors or 3TF contactors andwith discharge devices forthe fast discharge of the ca-pacitors (4EJ99 dischargereactors or resistors). Forconnecting the modules to-gether and for the connec-tion to the power systemvia cable, each 4RF5.. mod-ule has a 60 mm busbaradapter system with cop-per bars E-Cu 30 x 10 mmmounted at the front.The module construction isidentical for4RF56 p = 5.67 %4RF57 p = 7 %4RF58 p = 8 %4RF59 p = 14 %4RF53 with combined reac-tors.


The mounting holes on the4RF5.. modules are univer-sally suitable for 20 mmand 25 mm pitch.In Siemens power factorcorrection units supportingpillars with 20 mm pitchand thread entries for self-tapping screws are used.Two drawer bracketswhich must be firstmounted on the supportingpillar are used with each4RF5.. module.

The 4RF5.. modules are sim-ply inserted into the sectionon these drawer brackets andmounted on the supportingpillar with self-tapping screws.See page 7/5 onwards forcomplete units formed from4RF5 modules.

The module width for 600mm cabinet width is 536 mm.The module width for 800mm cabinet width is 720 mm.Therefore, the modules canbe passed without problemthrough the cabinet door open-ing, but the width of the baseplates should be taken into ac-count when selecting the sup-porting pillars.Where required, supportingpillars for certain cabinet typescan also be supplied on re-quest, see Accessories onpage 13/2.


On the power side the 4RF5..modules are connected viathe busbar system at thefront. The module busbars areconnected using extra copperconnecting lugs E-Cu 30 x10 mm. Under Accessories onpage 13/2 copper connectinglugs are available. For otherlengths the copper connectinglugs must be provided by thecustomer.One 4RF5.. module per sec-tion includes special busbarparts suitable for terminatingthe connecting cables.On the control side the 4RF5..module connection to thepower factor controller and tothe control voltage is providedby control lines which are tobe suitably laid (e.g. in cableducts) by the customer.

Technical data 11/2

Description


4RF14 tuned filter circuits areused in systems with a con-verter load > 50 % of the totalload or if the local power sup-ply utility requires filtering ofself-generated harmonics. Upto 90 % of the 5th, 7th, 11thand 13th harmonics are fil-tered. The filter circuits canonly be combined with powerfactor correction units with re-actor connected capacitors.

nDesign

Filter circuit units are suppliedready for connection in sheet-steel cabinets with ventilationslots and degree of protectionIP20.If required, they can be com-bined from separate filter cir-cuits which are designed forthe filtering of the 5th, 7th,11th and 13th harmonics. De-pending on the rating they con-sist of one or several branches.The individual branches com-prise:n Fuse switch-disconnector

4RF14 Passive Tuned Filter Circuitsfor Filtering of Harmonics

Description


The branches can be switchedmanually or via a central controlcommand. An electrical inter-lock only enables the branchesfor the higher order harmonicsto be switched in when thosefor the lower order harmonicshave already been switched incircuit.Filter circuits compensate theinductive reactive power withtheir capacitor rating, but theyare not controllable.If an improvement in thepower factor, cos ϕ , is also de-sired, power factor correctionunits with reactors can be con-nected in parallel.

nConnection

Each cabinet is separately con-nected via lines or power cableto the power system. The feed-ers are normally protected byLV HRC fuses.

nProject planning

The selection of the filter cir-cuits is made according to theharmonic currents of the con-verter on the feeder trans-former. Furthermore, the har-monic content of the higherlevel network and the short-cir-cuit reactance at the connec-tion point must be known.In order to specify a filter cir-cuit suitable for operation, anenquiry is required giving de-tails of the power system con-ditions. If necessary, the har-monics must be measured,see Catalog SR 10.2 in thecatalog index on pages 14/6and 14/7.

SIMEAS C Power Factor Controller

Description

nDesign

The controller is accommodat-ed in a housing for door mount-ing.Degree of protectionn IP54 frontn IP20 back, safe against fin-

ger contactOn the front there are twokeys for operation and a dis-play for showing the measuredvalues.The terminals and terminal dia-gram are found at the back.An optical RS232 interface isprovided for communicationwith a PC.

nConnection

The controller can be usedwith measurement voltagesfrom 200 V to 690 V AC50/60 Hz and with 1 A and 5 Acurrent transformers.The supply voltage is 230 V AC± 15 % 50/60 Hz.


The SIMEAS C power factorcontroller has six output relays.With these relays up to six ca-pacitor branches can be con-trolled in any step function ra-tio. The switching state is thenshown on the display.With a deviation of the powerfactor cos ϕ and at ± 60 % ofthe rating of the first capacitor,the capacitor required for thecorrection is computed andthe appropriate branch switch-ed in. The controller has thetask of switching all branches,as far as possible, with equalfrequency. The controller op-erates with time delays of 30seconds on switching in and 3seconds when switching off,as set ex-works. As with thedischarge time, both times canbe parameterized via the opti-cal interface.Switching in occurs only afterthe discharge period has ex-pired which is set to 30 sec-onds. With the SIMEAS Cpower factor controller there isa choice of the following fouroperating modes:n Display:

Automatic mode with dis-play of the measuredvalues

n Manual:Manual mode

n Input 1 2 3 4:Input mode

n Error:(View/delete error message)

4RY66 Controller Modulesfor SIMEAS C controllers

Description


4RY66 controller modules enable the doormounted SIMEAS C controller to be con-nected to the power factor correction uniton both the power and the control sides.The power factor controller is connectedto the controller module via a multi-polecontrol cable.

nDesign

The 4RY66 modules on a galvanizedsheet-steel chassis are fitted with anMCCB (Moulded-Case Circuit-Breaker)and a control terminal strip. Controllermodules with built-in fan assembly alsocontain three fans and a bimetallic thermo-stat.


The mounting holes on the 4RY66 mod-ules are universally suitable for 20 mmand 25 mm pitch. The 4RY66 modules aremounted on the supporting pillar usingself-tapping screws.The module width for 600 mm cabinetwidth is 536 mm or alternatively 580 mm.The module width for 800 mm cabinetwidth is 720 mm. Therefore, the modulespass without difficulty through the cabinetdoor opening, but the base plate widthshould be taken into account whenselecting the supporting pillars.If required, supporting pillars for certaincabinet types can be supplied on request,see Accessories on page 13/2.


Connection to the external power systemconductors L1, L2 and L3 is made via theMCCB. L1 provides the supply voltage forthe controller and the control voltage forthe controller outputs. L2 and L3 providethe measurement voltage for the control-ler (please refer to the operating instruc-tions for the controller).All contactors in the power factor correc-tion unit are connected to the control ter-minal strip in the controller module.Connection of the power factor controller,mounted in the cabinet door, is made viaa multi-pole numbered control cable.A control transformer must be employedfor system voltages > 415 V without exter-nal control voltage supply, see Accesso-ries, page 13/2.

Discharge reactors satisfy therequirements for permanentlyconnected discharge devicesas well as providing dischargetimes of just a few seconds.The 4EJ99 discharge reactorproduces only extremely lowlosses due to its high resis-tance on alternating current.When the capacitors areswitched off, very quick dis-charge is provided by the lowohmic resistance of about5 kΩ.

Degrees of protection IP provided by the enclosure

Degrees of protection forpower factor correction

Power factor correction unitswhich are designed as low-voltage switching device com-binations as per EN 60439Part 1, DIN VDE 0660 Part500, IEC 439-1, must beequipped with at least degreeof protection IP2X. This doesnot apply to units on mountingplates or modules intended forinstallation in existing enclo-sures.Detailed information on “IP de-grees of protection providedby the enclosure” can befound in DIN VDE 0470 Part 1,EN 60529.Power factor correction unitsand fixed compensation unitsin this catalog are equippedwith IP20, IP22D, IP40, IP54and IP65 degrees of protec-tion.The units are constructed insuch a way that, at an ambienttemperature of + 35° C (meanvalue over a period of 24 h),the temperature limits are notexceeded without auxiliarycooling.Degrees of protection higherthan those provided in thiscatalog require special design.The capacitor rating in each en-closure must either be re-duced or auxiliary cooling (fanor heat exchanger) must beimplemented.For this reason, degrees ofprotection higher than thosespecified in this catalog shouldonly be requested if this is ab-solutely essential at the site atwhich the units are installeddue to ambient conditions orfor safety reasons.

Designation

The degree of protection pro-vided by the enclosure is desig-nated by the IP code whichcomprises 2 digits and 2 op-tional letters (additional letterand complementary letter).The first digit designates theelectric-shock hazard protec-tion and the protection againstingress of solid foreign bodies.The second digit designatesthe protection against the in-gress of water. The additionalletter denotes the degree ofprotection with regard to expo-sure to dangerous parts; thecomplementary letter indicatesthe additional qualities forwater and weather protection(not relevant for power factorcorrection).The table above provides anoverview of the degrees of pro-tection specified in this catalog.

1) Certain protection against verticaldripping water is already providedas all enclosures have IP20 and IP40by means of a raised roof. Undercertain circumstances, however,splashes from dripping water maypenetrate the inside of the cabinet.

2) The degree of protection IP22D isimplemented as follows:Ventilation slots in the door coveredwith 1 mm protection grid, slots inroof covered with 10 mm protectiongrid and prod-proof roof metal design.This promotes heat dissipationthrough the cabinet roof.Foreign bodies > 1 mm can onlypenetrate the cabinet roof if theyenter the unit from the bottom tothe top through the roof metalconstruction. The first digit here is2 for this reason only. The degree ofprotection IP22D therefore is theoptimum solution for most installa-tion sites with regard to heat dissipa-tion and degree of protection.

Maximum permissible voltages on 4RB power capacitors

Continuous voltages

Power capacitors must be suit-able for operation with the volt-ages specified in the adjacenttable.The overvoltage values whichare permissible without notice-able damage to the capacitordepend on their duration, fre-quency with which they oc-cur, and the capacitor tempera-ture. It is assumed that theovervoltages in the tablewhich are higher than 1.15times UN occur 200 timesthroughout the operating timeof the capacitor.

Note:

In systems without reactors, the rated voltage UN of thecapacitor can always coincide with the rated voltage ofthe system in which the capacitor is operated.It is not necessary to use 4RB capacitors with a higherrated voltage UN (e.g. 415 V AC or 440 V AC) in a systemwith a certain rated voltage (e.g. 400 V AC 50 Hz).

In systems with reactors, the voltage increase whichoccurs at the capacitor terminals as a result of connect-ing the reactor and capacitor in series must be consid-ered.The voltage Uc at the capacitor terminals is calculatedusing the formula:
