Abstract
In this paper, based on the analysis of the working principle of high-frequency current transformer (HFCT), a high sensitivity small HFCT is designed for partial discharge (PD) detection of cable intermediate joints, and the factors affecting the sensitivity of the sensor are analyzed. The results of simulation analysis and experiments show that the sensor has good linearity in the passband, and the gain in the frequency range of 1MHz5MHz can reach more than 44dB (150mV/mA), with high sensitivity, and can couple out the small partial discharge current, which has strong practical application value.
