Single Phasing Preventer is a unit that uses the combined principal of Voltage sensing and current sensing to determine the Single phase in a 3 phase circuit. This prevents the motor running in a single phase due to any of the fault Phase failure, loose connections etc. Vidyut Industries manufactures Single Phasing Preventer.
Vidyut Industries also manufactures wide range of remote control and indicators for dam gates, reservoir water level indicators and dam automation. Single Phasing Preventer can control motor from 1 HP to 50 HP. Potential free contact of 230 VAC, 5 amps is provided for the output for connecting in the trip circuit. This prevents the motor running in a single phase due to any of the fault Phase failure, loose connections etc. The Indications are provided to know whether the motor is drawing the current in all 3 phase or not. The unit is housed in a metal enclosure with base mounting facility.
