A Study on Performance Characteristic of Electric Equipments for High Speed Train by on-Line Test

시운전시험을 통한 고속전철 전장품의 성능 특성

An electric railway system is composed of high-tech subsystems, among which main electric equipments such as transformers, converter and traction motors are critical components determining the performance of rolling stock. We developed a measurement system for on-line test and evaluation of performances of Korean High Speed Train. The measurement system is composed of software part and hardware part. Perfect interface between multi-users is possible. A new method to measure temperature was applied to the measurement system. By using the system, measurement and evaluation for the performance of electric equipments in Korean High Speed Train was conducted during test running.
