Tapped Insulator for Condenser Bushing

Bushing Shaped Capacitive Sensor

It is used in Ring Main Unit (RMU) and Switchgear, for taking electricity, accurate measurement, control and protection of LV, MV and HV electrical power systemsby dividing input high voltage 10kv/√3 into output voltage 3.25V/√3 for phase sequence and 6.5 V /√3 for zero sequence as signal voltage, which is for background detection.Connectting with power supply box, it can output DC electric power with DC27V,15W.
