Zusammenfassung:Title screen
Insulation destruction is one of many failure reasons of power transformers which belong to the most expensive and strategically important components of any electrical energy system. Insulation damage due to short circuit currents can cause an emergency situation at any moment. Thus, the reliable control of winding state is an important task of a modern power engineering technology. The paper deals with the experimental research of the pulsed method of transformer winding control. A new approach to winding state control technology is described. The proposed method is based on short (compared with a typical pulsed technology) probe pulse and front pulse durations. The experimental results of sensitivity growth at decreasing front pulse duration are shown. The experimental equipment and measurements are described. A comparison of the experimental results of the proposed pulsed method and FRA is given. It is shown that shorter front of probe pulse duration allows upgrading sensitivity of the diagnostic procedure.
