Abstract

Remote online monitoring system of power system lightning current is a data acquisition equipment of natural lighting current waveform for power system, which applies the Rogowski coil to transform the lighting current to voltage signal and realizes the high-speed data acquisition and wireless data transmission of lightning current waveform. Special server software is used to display waveform and determine the lightning type and fault mode. The equipment is installed on transmission line or lightning rod. Four sets of lightning current waveforms have been recorded during 2 years' field operation. Compared with the laboratory impulse current waveforms, the natural lightning current waveforms have the wave head of less than 1 μS and the violent vibration of wave amplitude.
