Built-in current transformers

QUESTIONNAIRE FOR THE INTEGRATED CURRENT TRANSFORMERS

Our company is producing integrated current transformers TV-TM-35 type for power transformers, high-voltage switches, and electric reactors. Transformer can be used in transformer oil, air, and insulating gas.

The transformer consists of a toroidal magnetic core from electrical steel with copper secondary winding. For measuring transformers can be used magnetic cores from amorphous and nanocrystalline alloys. The coil can have a tap to change the transformation ratio.

Standard characteristics of transformers TV-TM-35 type:

Rated voltage input, KW

10, 35, 110, 220

Rated primary current, A

50 – 18000

Rated secondary current, A

1; 2; 5

Accuracy class

0,1; 0,2; 0,2S; 0,5; 0,5S; 1; 3; 5; 10; 5P; 10P
