Abstract

This paper describes the transmission method of an information using communication networks between RTU(Remote Terminal Unit) and PCU(Protection and Control System) of the DC switchgear for Light Railway Vehicle. Also the test result carried out in the laboratory was represented. In this test, transmission signal waveform, polling time, response time and request/response frame between RTU and PCU were measured. The field test including the measurements of analog signal and status of the digital logic operation of PCU was conducted in Gyeongsan Test Track.
