Reactive Power Classification

Inductive reactive power: The current vector lags behind the voltage vector by 90 °, such as in electric motors, transformers, thyristor converters, etc
Capacitive reactive power: The current vector leads the voltage vector by 90 °, such as capacitors, cable transmission and distribution lines, etc
Fundamental reactive power: reactive power equal to the power frequency (50HZ)
Harmonic reactive power: reactive power that is not equal to the power supply frequency
