Partial Discharge Monitoring

Insulation degradation in bushings and windings is influenced by various electrical, thermal, mechanical and environmental stress factors over many years in service.

Partial discharge (PD) activity is a reliable indicator of insulation condition in transformer bushings and windings, as it is often a sign of insulation defects that can potentially cause failure.

We offer you a convenient solution for on-line temporary PD monitoring on power transformers to trend and assess PD activity over periods of time, so that you can perform additional diagnostic measurements to locate insulation defects and perform condition-based maintenance.
