Wide Frequency Band DC Corona Current Measurement and Analysis of Bundle Conductor Based on UHV Corona Cage

Abstract:

A wide frequency band DC corona current measurement system is introduced in this paper. GPS technology is applied to make sure that the voltage and current signal are collected synchronously. The wide band corona current signal is transmitted to the lower computer by the wireless network of 300M/s. The wide frequency band DC corona current waveform was gained in the Ultra High Voltage (UHV) Test Base in Wuhan, which can reflect the high frequency pulses of the corona current, and corona currents of 6 bundle conductor LGJ630-45 in dry and rain (rain rate 20mm/h) conditions are gained. The corona current in the rain condition is much larger than that in the dry condition.
