TRANSCRIPT
DescriptionThe transformers are cast in epoxy resin and designed for insulation voltages from 36 kV to 40.5 kV.The transformers are designed as single-or-multiple turn transformers, with one transformer ratio, or with the possibility to be switched over on the secondary or primary side.The number of secondary windings are from 1 to 8 (usually 2 secondary windings), depending on the combination of parameters (such as the accuracy class, short-circuit current, overcurrent factor…).The secondary windings are used for measurement or protec-tion purposes, or for special use (testing winding, „X“ class windings ..). One terminal of each secondary winding used and one terminal of short-circuited and not used winding have to be earthed during the transformer operation.The secondary windings are lead out into a casted secondary terminal board. The transformer can be mounted in any posi-tion. The transformer are fixed by four screws, the M8 bolted earthing clamp finds itself on the transformer base plate.
Rated primary currents are 10;15;20;25;30;40;50;60;75;100; 150;200;300;400;500;600;750;1000;1250;1500; 2000;2500 A.Other primary currents can be agreed with the manufacturer.Rated secondary currents...5 A; 1 A (possibility to combine different values in one transformer)Rated frequency ... 50 Hz; 60 HzThe transformers are designed and manufactured in conform-ity with the following standards and recommendations:IEC, ANSI, VDE, BS, GOST and CSN.Cantilever strength: 5 kNPermissable torques for screw connectionsM5 max /Nm/ …3,5 min /Nm/…2,8M8 max /Nm/ …20 min /Nm/…16M12 max /Nm/ …70 min /Nm/…56
