Transformer Turns Ratio Testing & Excitation Current Measurement

The turns ratio test is one of the most commonly performed and standardized tests on all transformer types, which is performed both in the factory and in the field. It applies and measures voltage on the HV transformer side and measures the induced voltage on the LV transformer side.  The excitation current test is usually done with the turns ratio test. It can indicate potential problems in both the transformer core and windings.

This webinar will explain the theory behind both tests, show practical examples and case studies of problems that can be detected with them, and provide information about the instruments used for performing them.

The webinar will be held in the English language. The number of participants is limited to 250.
