FIELD: electricity.
SUBSTANCE: method is described to measure phase capacitance of an electric network with isolated neutral, which includes alternate measurement of short circuit currents in each phase and differs by the fact that additionally angles are measured between vectors of short circuit currents and vectors of voltages that arise during short circuits on the neutral, using which they calculate phase capacitances.
EFFECT: method increases accuracy and eliminates errors when determining phase capacitances of an electric network.
