Measurement system of TTX(Tilting Train eXpress) network

Presently, as the feasibility study shows that trans-Korea railway and trans-continental railway are advantageous, interest in high-speed railway system is increasing. Because railway vehicle is environment-friendly and safe compared with airplane and ship, its market-sharing increases gradually. TTX (Tilting Train eXpress) has been developed by KRRI(Korea Railroad Research Institute) for last 5 years to satisfy the need. An electric railway system is composed of high-tech subsystems, among which main electric equipment such as transformer and converter are critical components determining the performance of rolling stock. We developed a measurement system for on-line test and performances evaluation of TTX network line.
