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, “Repair or replace? The $64,000 (or much more) question facing utilities,” for in-depth information on how to extend the life of your transformers.
