Answer Posted / Mohsin Iqbal
The stage of an Automatic Power Factor Controlling Relay (APFCR) can be determined by observing its operational status and the corresponding power factor readings. The stages typically include: 1) Inrush Current Limiting Stage, 2) Capacitor Charging Stage, 3) Power Factor Correction Stage, and 4) Overcompensation Stage.
