Abstract：the traction transformer is used to transform 25KV electric contact the web for the supply voltage for the traction motors and other auxiliary motor, electric locomotive work, is an important part of electric locomotive power supply device. This paper presents a test of traction transformer current (or voltage) locomotive harmonic scheme. Correct the test current (or voltage) harmonic components contained in the flow system, design of variable design and manufacture and supply of the main transformer, is very important.
