... нованного на сравнении фазового угла между током и напряжением обмотки на фиксированных частотах. Abstract In the article the issues of technical diagnostics of power transformers windings are considered. Results of windings condition assessment using impedance measurements, frequency-response analysis and fi ed-frequency phase parameters measurement are presented. It is noted that the method for winding condition ...
