Temperature characteristics is very important in electrical system of high-speed train. It is because insulation level is changed according to electrical system temperature characteristics. Major items of electrical system are transformer and traction motor. These items have function to run and brake electrically high-speed train. This paper presents test results of temperature characteristics on high-speed line during high-speed train run at maximum speed.
