Partial discharge testing and monitoring

Partial discharges cause insulation defects and eventual failure in your electrical equipment

Reliable condition assessment

Partial discharge (PD) is considered one of the major contributors to the degradation and failure of insulation systems in electrical equipment. 

Compared to other dielectric diagnostic methods, PD measurement and analysis allow you to effectively and reliably assess the insulation condition of a number of high-voltage assets. They are performed during factory acceptance, on-site commissioning and routine maintenance testing to detect insulation defects and assess risks.

Timely corrective action

Since PD activity is often present well in advance of insulation failure, PD measurement and analysis allow you to make informed decisions regarding the timely repair or replacement of equipment to ensure operation reliability.
