Development of DCPD Detection Instrument for High-Voltage Storage Capacitor

  • Received Date: 01 Nov 2005
  • Publish Date: 25 Dec 2006
  • Based on the RLC balance resistance detection and Δt(time interval between two consecutive discharges) analysis techniques,a DCPD(direct current partial discharge) detection instrument for high-voltage storage capacitors was developed to estimate the performance of a high-voltage storage capacitor.This instrument consists of a good anti-jamming hardware with a 60 to 250 kHz bandwidth and a DCPD analysis software with signal processing and statistic calculation functions.A DCPD test was carried out on capacitor models respectively with classical inner,contact and overlapping defects.The Δt distribution and discharge spectrum show that the DCPD detection instrument can detect partial discharges and find out the reason of partial discharges and the insulation state of a high-voltage storage capacitor.
