ELECTRIC CURRENT DISTRIBUTION IN AUTOTRANSFORMER SYSTEM

Abstract

The article exposes a method of calculation of current distribution within autotransformer system of power supply of single and double track railways with voltage between wire network and rails that differs from the voltage between feeding wire and rails. The presented equations result in simplified formulae that allow calculating the load on transformer’s units. The calculations based on formulae show that compensating current doesn’t influence the load of transitional autotransformers. The load on the autotransformer which neighbors substation on one track depends on the load on the autotransformer which neighbors the substation on the second track.
