A quick guide to identifying HV infrastructure deterioration through partial discharge monitoring

Partial Discharge is the most common cause of disruptive failure of switchgear, with research showing that 85% of disruptive failures in HV and MV equipment are linked to PD damage. Detecting and measuring PD activity gives a unique insight into the condition of HV assets without the need for expensive shutdowns or invasive testing technologies.

In this quick guide, we explore the effects of Partial Discharge on HV assets and the solutions that can be put in place to monitor asset condition.

Topics include:

• Understanding Partial Discharge
• Monitoring techniques
• Partial Discharge monitoring in practice
