Inspection and Test Plan for Power Transformer

This test can be measured after the current has not passed through the transformer for several hours, reaching the same temperature as its surroundings. Winding resistance is calculated by measuring the voltage and current simultaneously , with the current as close to the rated current as possible.

ALTERNATIVE TESTING MINIMUM REQUIREMENTS

A transformer test may have particular sensitivities to test preparation, test lead connections, and the test environment. A good example is a power factor/dissipation factor/tan δ (i.e., PF/DF) test. If the test result is not accurately compensated for the temperature at which it was performed, a comparison to previous test results and the application of a standard’s suggested PF/DF
