Why do we need effective electrical maintenance programs?

This presentation by Rudy Wodrich of IRISS, Inc. takes a deep dive into why electric power maintenance programs are essential for all organizations. Wodrich explains why calendar based maintenance programs are a "bad bet," how you can use technology to detect the early warning signs of most types of equipment failure, and how performing a criticality analysis helps you prioritize condition based monitoring activities and which technologies to use for inspections.

This presentation was filmed in Chicago during November 2019 as part of the Electrical Reliability Roadshow, and is available in its entirety only for members of the Electric Power Reliability Alliance.

How does ultrasound detect Partial Discharge (PD) in high voltage electrical assets?

Published with thanks to SDT Ultrasound Solutions:

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.”
