Reference current transformers TOLK-10, TOLK-10-2

Transformers TOLK-10 are designed to transmit a signal of measuring information to measurement, protection, automation, signalling and control devices, as well as to test the performance of the maximum current protection in the absence of load in the primary circuit.
Transformers TOLK-10-2 are designed for transmission of measuring information signal to measuring devices.
The transformers are designed for installation in high-voltage mine complete switchgears in networks of voltage up to 10 kV in coal and oil shale mines, hazardous by gas and dust.
Transformers have climatic version "O", placement category 5.1 in accordance with GOST 15150, transformers TOLK-10-2 can be manufactured in climatic version "U" , placement category 2.
