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
