Prok Dvs an ISO 9001:2008 Company indigenously develops the power system protection relays and panel meters for power system. μP based Zero sequence voltage relays are the state of the art design, to monitor and protect the costly equipments against unbalance voltages.
The Relay Continuously monitoring all the three phase Line to Line Voltages, if any abnormal condition persists in the system internal Relay activated with predetermined set value of definite time.
The Unit Displays Line to Line Voltages on LCD display, Healthy and Fault /Trip status Information through LED Display.
