Total destruction of windings is one of many failure reasons of power transformers which belong to the most expensive and strategically important components of any power engineering system. Mechanical displacements and following insulation damage due to short circuit and inrush currents can cause an emergency situation at any moment. Thus, the effective control technology of winding state is an important task of a modern power engineering technology. The paper deals with the experimental research of effectiveness increasing 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 efficiency growth at decreasing front pulse duration are shown. The experimental equipment and methods are described. It is shown that duration of probing impulse has optimum value around 100ns. It is established that it is possible to do a condition control under operating voltage. It is shown that single stage measurement technology is further step in the development of effective winding control technology. |
