Description: Automatic Power Factor Correction Relay (APFCR) offered by our company is used for true RMS measurement. The PF is measured for any one phase from the voltage sensed between phase and neutral and current in the same phase, using digital signal processing (DSP) methods. The technical specification of this relays includes supply voltage - 230 V AC, 50 Hz nominal between phase and neutral; supply voltage range - 80 to 270 V AC; current - 5 A from CT secondary; output switching capacity -5A @ 230 V AC resistive load; number of stages - standard 6,8,10,12 and 16 stages; target PF setting - from 0.8 (Lag) to unity in PF mode, and 0.8 (Lead) in VAR mode; reconnection time delay - settable at site, from 5 seconds to 120 seconds; minimum current - 5% of rated CT primary in PF mode, and 1.0% in case of VAR moe; mounting - flush mounted using clamps. The relays are available in dimensions of 144 x 144 mm bezel, 138 x 138 mm cutout size.
