Experience shows that Partial Discharge (PD) activity is a contributing factor in more than 80 percent of disruptive substation failures. Ultrasound can detect PD throughout the substation, from switchgear to transformers to cables. This video, presented by Allan Rienstra of SDT Ultrasound Solutions, is an overview on how ultrasound works, its strengths and limitations, and how it can be used to detect PD in your substation equipment. “PD may be intermittent, or it may vary in intensity over time… but once it starts… the damage is always going to increase; It’s not going to get better.”
