Analysis of Experimental Railway Point Electric Heating System

The article gives an overview on different point electric heating systems. Based on previous researches some new solutions are proposed to fulfil shortages of current solutions. Existing methods of point electric heating control are reviewed and compared; their disadvantages are listed. As a proposed solution to the described problem, an experimental point electric heating control system is proposed and described. Experiment of controlling point electric heating system using pulse-width modulation method is set. Conclusions show that the approach of introducing pulse-width modulation allows to control point electric heating in more efficient way - using program code, control system will adjust heating adjust time intervals when the heating is turned on and off.
