TR-EVT-10 electronic voltage sensor is suitable for 10KV column circuit breaker, 10KV switch cabinet, load switch, gas-filled cabinet and solid cabinet. It is mainly used to detect line phase sequence and zero-sequence voltage, direction judgment and phase angle protection. Adopting the principle of capacitive voltage division, it is an AC sensor that conforms to the technical specifications of the primary and secondary fusion of the State Grid.

Simplify the system structure, directly output standard small signal without secondary conversion, directly input secondary equipment through A/D conversion, reducing the source of errors;

The magnetic core has high permeability and low temperature drift. In the temperature range of -40℃~+70℃, especially at -40℃, the variation of the error meets the standard requirements

The output internal resistance is small, which overcomes the error caused by the cable and can be adapted to various cables;

The composite film capacitor with CVT transformer structure has good long-term stability;

The accuracy changes little due to the influence of ambient temperature.
