High-voltage storage capacitors (hereinafter call capacitors for short) have been widely used in pulsed power technology. In accordance with the actual work conditions of capacitors, direct current partial discharge (DCPD) detection was put forward. The whole test system was based on the impedance balance circuit characterized by good configuration and anti-interference ability. Through DCPD detection...
As for storage capacitor charged under DC and discharges with a large pulse, partial discharge detection under DC is fit for its work condition. The paper presents the principle and construction of a detecting instrument for DC partial discharge (PD) within storage capacitor as well as the results of the first stage experiments. In order to increase the sensitivity of measurement system for large...
