How to reduce the risk of transformer failure. On-load tap changers are often the culprit when power transformers fail. Trouble with mechanical components and coking of contacts are frequently at fault. In this video, you can explore the design of some of the most commonly used tap changers and discover the strengths and weaknesses of each. You will also learn about options to repair or retrofit troublesome tap changes and maximize transformer life. Download the white paper,...
This video highlights a series of tests held at EPRI's laboratory in Lenox, MA, that measure the stress points and tolerances of power lines, poles and other equipment in an on-going research effort to help make the nation's grid more resilient.
