WHAT IS EPRA?
The Electric Power Reliability Alliance was formed for electric power reliability professionals.
We are a “practitioner-to-practitioner” collaborative community, bringing proven and practical resources and shared experiences to practitioners in the industrial and commercial markets.
We share tools, resources, and experiences and work towards better practices to advance electric power reliability—specifically for industrial and commercial organizations.
Members receive full access to the Resource Center Library and articles, videos, blog posts, and podcasts produced by EPRA and EPRA members. Enjoy three free articles, with access to the entire library with a free trial membership.
Power cables are one of the most commonly overlooked power system assets and are, by default, typically addressed reactively after failure. They are also one of the most misunderstood. This article provides insight into how new scientific findings on cable care address these misunderstandings.
Spatial Resolution is also known as the Instantaneous Field of View (IFOV) or Spot Size. The limitations of the spatial resolution are due to the size and expense of the focal plane array (FPA). The FPA of many moderately priced cameras will have an array of 320 x 240 or 160 x 120 detectors. This may make it difficult to determine the temperature of small targets at a long distance.
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.
