Circuit diagram of PF relay. In order to measure electrical power the relay needs to receive the line voltage and current from a current transformer (CT) installed close to the metering point, if possible. To measure reactive power at the power factor relay especially, it must be ensured that the vectors of voltage and current are shifted by 90°.
The length of the voltage vector represents the magnitude of the voltage across the capacitor, while the length of the current vector corresponds to the magnitude of the current flowing through it. The angle between the voltage and current vectors is always 90 degrees in a purely capacitive circuit. The phasor diagram helps to visualize these relationships and provides a clear …
