Transformer Troubleshooting

SKU: TDTTR00CEN
Duration: 1.00 Hr

The purpose of this course is to teach techniques for troubleshooting single-phase transformers and three-phase transformer banks. The course demonstrates how to identify a faulted transformer. It also demonstrates how to isolate transformers and how to test for proper no-load voltage. At the conclusion of this course, participants should be able to identify a faulted single-phase transformer, isolate it, and test it for proper no-load voltage. They should also be able to identify a faulted transformer in a three-phase transformer bank, isolate the faulted transformer, and test it for proper no-load voltage.
