Efficiency of the 3-phase system to provide energy under low frequency induction heating of CWRs

Abstract

In this paper the efficiency of heating of continuous welded rails (CWRs) under track laying when 3-phase low frequency supplying system is applied has been carefully considered. On the basis of computations confirmed by the investigated results, for different heaters location as well as different voltage phase shifts, the conclusions concerning proper selection of the structure of the energy supplying systems are formulated.
