摘要
This paper presents an improved technique to generate damped AC voltage for on-site PD detection on distribution power cables. The proposed technique is based on conventional frequency-tuned series resonant system and two additional high-speed switches. In order to reduce the size and weight of the proposed damped AC test system, electric simulation by Simulink and heat simulation by ANSYS are carried out to determine the system parameters. High-voltage test on two 10kV XLPE cable segments was conducted to validate the proposed technique.
