EN The diagnostics has in the power transformers operation the irreplaceable position. Transformers are exposed to series of diagnostic measurements and these tests are recently replenished with additional methods. The acoustic responses sensing from the transformer tank surface is included in these methods relatively often. The transformers are usually exposed at these measurements to alternating voltage. The usage of acoustic methods in the diagnostics of insulating defects caused by over-voltage impulses is less usual. But cumulative demands on reliability of power devices lead to the requirements on the development of insulating system diagnostics associated with new methodic application. Therefore the acoustic responses monitoring during surge test on transformers was introduced.
