Our voltage transformers with built in sensors are designed for pole tops and kiosks and are intended to be used for low power remote control- measurement applications in medium voltage networks with the range 3-27kV.  Voltage sensors are of resistive type for eliminating the saturation risk in situations of single phase earth fault in a network with isolated neutral.

Hughes Power System voltage transformers
