INTRODUCT I ON

IB 6 e 1 0 2 .8-1 bPage 3

The electronic trip control unit described in this publication is a solid state, microprocessorcontrolled unit, used in conjunction with a power circuit breaker to protect power systems . Thepower circuits being protected are typically 3-phase, with and without a neutral connection, 50 or60 Hz with AC RMS voltages between 20 8 and 600 volts . The unit will control continuouscurrents as high as 4200 amps, while ground currents may not exceed 1200 amps .

The MPSC-2000 trip control unit measures current to an accuracy of within 1% of the circuitbreaker rating. The Voltage Interface Module (VIM) option measures voltage to an accuracy ofwithin 1 °!o of the circuit breaker rating, and power to within 2% of the circuit breaker rating .

The trip unit is completely self-powered, taking the the tripping energy from the current throughthe breaker without any auxiliary power supply . A battery is supplied for programming the controlunit while the circuit breaker is deenergized .

The complete control of the circuit breaker is achieved by a system comprising :(a) current sensors, (b) an electronic trip control unit, and (c) a magnetic latch trip device .

The sensors , the electronic trip control device and magnetic latch are mounted as an integral partof the circuit breaker to pr ovide complete pro tect ion for overcurrent, short circu it and groundfaults . Internal diagnost ic circuitry is provided to determine and visually identify the cause ofcircuit breake r tripp ing , as overload , short circuit or ground fau lt .

PUMPPROCEDURE FOR FI ELD TESTING THEM PSC-2000 S OL ID STATE TRIP SYSTEM

There are two ways to evaluate the MPSC-2000 solidstate trip system : primary current injection through thebreaker main contacts ; and secondary current injectiondirectly intoAhartrip device. Primary injection has theadvantage of testing the current sensors and magneticlatch also .

The following is a procedure for performing this fieldtesting .Notes :

1 . Refer to time current curves TD-9651, TD-9652 andTD-9653 (also in this appendix) .

2 . When checking calibration, disable the functions notbeing tested, or set them at their highest threshold anddelay values . It is 2SeeC laOly tEportant to disable theGround -function when testfng the other elements toprevent false tripping.

3.3he circuit breaker must be closed before each testbelow.

4 . Following each test, check the MPSC-2000 eventregister , to ensure that the correct element tripped thebreaker , especially if test results appear to be incorrect .

section .5 and 6gin the main 'body of th isinstruction bulletin for instructions on setting the MPSC-2000.

6. These procedures are written for primary injection . Ifthe trip device is being tested by secondary currentinjection, use a special test cable available from AFBand follow the special instructions contained therewith .

Instantaneous or Short Time Threshold Test

1 . Either disable the trip elements not being tested, orset them to their highest threshold value . Set the LongTime Delay to its maximum setting . Set the Short Timedelay to its minimum setting for Short Time tests .

2 . It is recommended that the Range Selection be set toits lowest value to minimize the current required for thistest; however, it may be set to either available value .

3. Set the threshold and delay of the trip element being.ested (again, it is recommended that a low value beused) .

4 . Test for the actual threshold by increasing test currentuntil the breaker trips . It is important to increase thecurrent fast enough so that the breaker will not betripped by the Long Time element prior to completion ofthe test.

5 . The threshold tolerance is +/- 10% on all selectorswitch settings .

Long-Time Threshold Tes t

1 . Either disable the trip elements not being tested or setthem to their highest threshold value .

2 . It is recommended that the Range Selection be set toits lowest value to minimize the current required for thistest ; however, it may be set to either available value .

3. Set the Long Time threshold . Set the delay to itsminimum value .

4. Test for the actual threshold by increasing test currentuntil the pelf Monitor light begins to blink quickly . Thebreaker should trip about 8-13 seconds later.

5 . The threshold tolerance i s +1- 10% on all se lecto r

Long-Time Delay Tes t

1 . Position other trip element selectors at their highestthreshold value .

2. It is recommended that the Range Selection be set toits lowest value to minimize the current required for thistest; however, it may be set to either available value.

3 . Set the Long Time threshold to its maximum setting .

4. Set test current so that it represents three times (3X)the trip system Range Selection setting . Delays shouldbe as follows :

Ground Trip Delay Tests

Ground Trip Delay tests_are performed by injectingcurrent through a single phase of the breaker, whichappears to be a ground fault to the trip device. Onbreakers with 4wire ground . on - double-endedsubstations, a remote neutral sensor must be used fioperform this best.

1 . Disable the other trip elements or set them at theirhighest threshold value.

2. The Range Selector has no influence on groundsettings.

3. -Set the GND PICKUP to the min imum ava ilableg round setting .

4. Set test current so that it represents three times (3X)the GND PICKUP setting. Delays should be as shown inthe chart below.

Response With ST 12t Behavior Defeated ("DES" or "OUT")MPSC-2000 : M PS-C-3( I NSTIT); MPS-C-4(ST .LT) ; and MPS-C°5(ENST,d7,6T)

1 : This log-ooq~r~ph depicts the short-time response without Izt behavior . It the p`t choracteriis enabled ("I!T" or "IN"), then refer to TD-9653. If a ground function was odded to the tripsystem, then also refer to time-current curve TD-9652 for ground response .

2 : These purr?, are typical of single and three phase power functions for 50 ;'60 Hz systems. Ifa trip function is not available on your unit, then ignore the corresponding curve . Curves werecalibrated for a temperature range of 10-40 'C. The reset time for any trip function is 50 msmaximum .

TE 3: For any time band, the lower and upper limits define the time interval for which tripping willoccur at a given ,multiple of rating current . If current exceeds the INST threshold, then theunit will trip the breaker by means of the instantaneou s-Function . If current less than theINST threshold but greater than 90% of the ST threshold persists for a time up to the lowe rST band limit, then the unit will trip the breaker through the short time lunation . If currentgreater than the the LT threshold but less than 90% of the ST threshold persists unti lthe lower LT band limit, then the unit will trip the breaker through the long time function .

4 : Use the circuit breaker only within its published short circuit current rating . Since, all tripvalues are selectable, they must be chosen to match the requirements of your power system .

5: The instantaneous, short-time, long-time, and ground tripping functions operate independently .Trip thresholds are set as multiples of the rating current . The rating current is e0he r50% or 100% of the trip system rating . EXAMPLE : An 800A K-Line breaker is set at a50 % rating of 400A. If its threshold multipliers are (12) INST, (5) ST, and (0 .8) IT, thenthe thresholds ore 4800 A . 2000 A, and 320 A. respectively . All units are shipped with thefollowing factory settings (unless ordered differently) :
