Power transformers are large, high value items which represent a significant investment of capital and other resources in their specification, procurement and operation. This presentation will discuss both 'standard' and 'novel' electrical tests on power transformers and the benefits to owners/operators of the data obtained: from dissolved gas analysis and power factor through to frequency response analysis and moisture assessments. Understanding the true condition of a power transformer and its consequent ability to perform its function is the basis for predicting useful life.
