摘要

Transformers are an important element in industrial applications. They are used, for example. in industries related to electricity transportation. The electric systems in countries such as Germany, Switzerland, France and Spain, where there is a traction power supply system AC power transformers are part of the transformation of electricity on the rolling stock. The most common application for these single-phase units are designed in such a way as to be able to work for the rolling stock traction vehicles for the various types of power supply systems (25kV / 50Hz, 15kV / 16,7Hz, 3000V / DC). This article describes methods for the identification of elements of equivalent circuits of transformers, as well as the analysis carried out measurement errors in determining the parameters of equivalent circuits of transformers.
