APPLICATION
JRR 011 is used to trip (dis-connect) capacitor bank from
the line during lead power factor in the system.
PRINCIPLE OF OPERATION
The R – Phase line current input to relay is derived from the line CT. The R – B lne voltage scaled to relay rated voltage using transformer. The relay measures the phase angle between R – Current and R – B Voltage, the output contact operates when PF reaches lead condition release when PF reaches lag condition after fixed operating delay of 60s.
The Aux supply required for the operation of relay is derived from the voltage input hence no need of dedicated power source.
The relay displays power factor, line frequency, phase angle between line current and voltage.
