Phase difference measurement method and device based on instantaneous reactive power

The invention provides a phase difference measurement method and a device based on instantaneous reactive power. The method comprises the following steps: 1, acquiring a first instantaneous current value when the phase is phi and a second instantaneous current value when the phase is zero at any t m...
