Built-in 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.
