Partial Discharge & Circuit Breaker Asset Management

Detecting and avoiding preventable failures

BY JAY GARNETT, Doble Engineering Company

While metal clad switchgear can be very reliable, sometimes operating for over 50 years, throughout the aging process, this group of electrical disconnect switches, fuses and circuit breakers can experience issues such as moisture ingress, animal intrusion, enclosure rusting, and insulation deterioration. One efficient approach to detect incipient failures is partial discharge (PD), a leading indicator of various failure modes. Using both acoustic and...
