Partial Discharge Monitoring
Because partial discharge (PD) activity is often present well in advance of insulation failure, it provides the most evident indication of defects and deterioration in transformers, rotating machines and switchgears.
Asset managers can evaluate partial discharge activity over time and make informed strategic decisions regarding the timely repair or replacement of the equipment before an unexpected outage occurs.
There are several different types of partial discharge measurement practices including classical electrical PD measurements, ultra high frequency PD measurements, and ultrasonic PD measurements. To learn about the different partial discharge measurement styles – download this handy guide.
