Product Details

  • Neutral Displacement Relay

    Model No : MPND

    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.


    • Accurate and reliable measurement .of residual voltage.
    • Display of voltage magnitudes, using 8 character 2 line LCD
    • User friendly Setting Parameters through key pad switch
    • Wide range for Selection of residual voltage
    • User configurable Definite tripping time (DMT)
    • Fast tripping response(<500mS) when Phase and Neutral are Interchanged
    • Industrial Rugged design in Din rail mounting as well as Panel Mounting.
    • Healthy, Trip Status provided through LED visual indications.
    • Auto Reset provided on Healthy voltage resumption
