Current measurement methods for distribution network can not eliminate the effects of damping resistance and voltage transformer short-circuit impedance during the measurement of the capacitor current, resulting in a large measurement error. Therefore, a precisely measurement method of capacitance current for resonant grounding distribution network is presented in this paper. A variable frequency current signal is injected into the distribution network through the zero-sequence voltage transformer of the distribution network. The returned voltage signal is measured from the voltage transformer...
