LEAD POWER FACTOR RELAY JRR 011

OVERVIEW

    Features

  • Software based design
  • Display of Power factor, Phase angle
    and frequency
  • Dust proof enclosure
  • Draw out type

Application:

JRR 011 is used to trip (dis-connect) the capacitor bank from the line during lead power factor in the system.

LEAD POWER FACTOR RELAY JRR 011

Principle of Operation:

The R-Phase line current input to the relay is derived from the line CT. The R – B line voltage is scaled to relay rated voltage using transformers. The
relay measures the phase angle between R-Current and R-B voltage. The output contact operates when PF reaches lead condition after fixed operating time
of 60s. The output contact, 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.
