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.
Learn how the safety features of dry-type transformers allow them to be placed inside buildings with high voltage limits to bring power closer to end-users in big cities more efficiently. For more information about dry-type transformers, watch this webinar: Overcoming urban power distribution challenges with technology innovations.

internal wiring of the transformers should be in complinace with NEC, sections related wire current capacity and the withstand to short circuit current. inaddition all wiring should be insulated and, when bolted connecions are made, the nuts should be visible.
