Partial discharge test equipment commissioning

The customer mainly produces 10kV primary and secondary fusion power equipment, and the partial discharge withstand voltage equipment is 50kV/30kVA; The laboratory is on the third floor; The plant is rented. Considering that the shield room will be more troublesome to move in the future, there is no shield room;

After the equipment arrives at the site, it is found that the interference is very large, and the background interference is more than 30 pC;

According to the analysis of our years of partial discharge commissioning experience, the interference source was determined and the rectification plan was proposed to the customer, who actively cooperated with the rapid rectification; After rectification, the background is 1.28pC without shielding room;
