Distribution Transformer Selection and Fault Diagnosis

Choosing the wrong transformer, or missing early warning signs, leads to premature failure and costly outages. This programme helps engineers specify distribution transformers correctly and diagnose problems before they become failures. Delegates cover sizing, cooling, protection and the tests that reveal internal condition.
