Figure 3. Single-tariff register Figure 4. Double-tariff register

Single-tariff registerRegistration with single-tariff registersis accomplished by means of acyclometer register, fitted with a7-digit display as standard (seefigure 3). The plastic cipher rolls,stepping drives and gear wheelsrun without lubrication on highlypolished shafts which at one endare pressed into a stamped andfolded part. A slidable plasticpart arranged on the left endenables accurate adjustment ofthe end play of cipher rolls and gearwheels. When being fitted,the register is pushed up against aboundary surface on the uppermeasuring system support andthen fixed with a screw.The nameplate is fixed onto thealuminium stamped stand, via ahook-in nose on the left of the registerand a screw on the right of thecipher cutout.

Two-tariff registerRegistration with two-tariff registersoccurs by means of a twinroll registerwith a 7-digit display as standard (seefigure 4). It works according to theswinging shaft principle. The registerbracket consists of a stamped andfolded part of 1.5mm thick aluminiumsheet. The two shafts each for cipherrolls and drives are at one end pressedinto the aluminium stand and at theother end held by a plastic part, whichholds the register bracket, the shaftsand clamps, the cutout blade relaywith its shielding, and the PCB.The nameplate is fixed onto thestamped aluminium stand via twohook-in noses on the right side of theregister and a screw at the lever of thecipher cutout on the left.The switch-over will be done by thesame voltage, to which the meter isconnected but on special request thisswitch-over voltage can be different.

Low-load settingThe low-load setting is adjusted withthe low-load screw (10). When it isoperated, a swiveling lever (9) fixed tothe voltage return of the R systemchanges its position relative to thecentre pole of the voltage core.In systems S and T adjustment tostandstill proceeds in the same waywith voltage connected.

Torque compensationFor torque balancing a screw (11) inthe return leg of the voltage system isprovided. By turning this adjustmentscrew the airgap of a magnetic shuntpath on the voltage system and hencethe voltage driving flux is altered.

Phase sequence compensationFor four-wire active energy meters arotating field lever (14) between therotor shaft and the T-system compen-sates the rotating field dependent errortorques on low load. Adjustmentproceeds at low-load connected inincorrect phase sequence.

Phase compensationTo set the 90 displacement betweenthe driving fluxes required on non-

inductive load, two copper vanes (8)are swung into the shunt gap of thevoltage core by turning the fixing shaft. Coarse adjustment of the phase angleis achived by opening the short-circuiting rings on the current core.

Braking forceThe braking force can be coarsely var-ied by swinging the braking systemabout its mounting point. Fineadjustment is achieved by means of asteel swivelling tongue (7) which actsas a magnetic shunt and, depending onits setting, weakens to a greater orlesser extent the magnetic flux actingon the rotor disc.

Starting/no-load settingThe starting on no-load setting isadjusted by means of the holdingvane (12) fixed to one driving element,which attracts the no-load hook (13)to be found on the rotor shaft. Theholding vane (12) is located in systemS only for four-wire active energymeters, for all other types it is locatedin element T. For accurate adjustmentthe distance between these two partscan be altered by bending theholding vane.

Transformer connected high precisionmeters Class 1.0 accuracy, according toIEC 60521

The load capacity of these meters is upto 600%.

They are suitable for invoicing largerquantities of energy in substations orfor heavy consumers, and as comparatoror standard meters for testing and adjusting meters in general service.

The programme covers all applicationsfor 120 and 200% load capacitycurrent transformers.

They can be equipped with up to 12(DIN version) or 4 (UTE version) auxiliary terminals for incoming andoutgoing signals.

To meet the requirements for Class 1.0with the various influence quantities:

- the rated speed is reduced bybraking the meter rotor.

- the drop of the error curve in the low-load range is minimized by the use of a current core material with low remagnetization losses.

- the error curve drop from the highest point on the curve to the load limit is reduced by use of acurrent shunt.

- the torque for meters for connection to 120% load capacity transformers is increased by 20% by means of reinforced voltage and current driving fluxes.
