Current transformer TLO-10 MH31

 
 

The main specific features of this design

TLO-10 MH31 current transformer for 6-10 kV is designed for installation in outdoor switchgears and in single-end service assembled chambers.

The current transformer ensures transmitting of the measuring information signal to the measuring instruments and protection and control devices to insulate secondary wiring from high voltage in alternating current electrical units for up to 10 kV voltage class.

Climatic modifications NF (temperate and cold climate), placement categories 1 under GOST 15150-69.

*Для трансформаторов с расширенным диапазоном первичного тока погрешности при токе 150 и 200 % номинального первичного тока не превышают пределы допускаемых погрешностей для 120 % номинального первичного тока.

**Для классов точности TPX, TPY, TPZ по ГОСТ Р МЭК 61869-2 значения номинальной вторичной нагрузки S2ном пересчитываются по формуле, В·А:

где  Rb– номинальное values for parameters резистивной нагрузки по ГОСТ Р МЭК 61869-2;

I2ном – номинальный вторичный ток, А.
