Abstract

Many rail transport providers operate and maintain a medium voltage distribution network providing power to trains, signalling equipment and stations. Transformers form an important part of the distribution network stepping voltage up and down. Rectifier transformers are used to provide DC for traction, usually stepping down from medium voltage levels. Mineral oil is essential for optimised performance of large transformers, providing the much needed cooling at high power operation and elevated core and winding temperatures. A representative rectifier transformer has been modelled for a realistic analysis of the 3D model constructed using exact manufacturer’s data for the geometry and coil arrangements. The results are seen to be in good agreement with the actual tests carried out during the commissioning of the transformer.
