Power Relays Dealers in Bidadi, Bangalore

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

We are offering lead power factor relay. Features software based design display of power factor, phase angle and frequency dust proof enclosure draw out type.
