Partial Discharge Monitoring of HV Transformers and Switchgears

About this service

Electrical discharges that do not completely bridge the electrode Cause deterioration and eventual failure of the insulation layer As per IEEE statistics Partial discharge is cause of 85 % of faults in High voltage Equipment.

  • Switchgear insulation is difficult to test during routine maintenance
  • Insulation failure can be devastating
  • Many failures of HV insulation are associated with Partial Discharges
