Abstract：The pantograph-catenary system is an important component of the electrified railway traction power supply system. The off-line phenomenon often occurs during the operation of pantograph-catenary system. The off-line phenomenon will lead to serious electromagnetic noise problem. Some off-line experiments were carried out with self-developed experimental platform under different experimental conditions. The frequency domain characteristics of contact current in off-line state were analyzed. The total current harmonic distortion rate (THD) was used to represent the characteristic of conductive electromagnetic noise caused by off-line phenomenon. The relationships between THD and loop current, contact pressure and sliding speed were obtained. The mathematic model of THD was established. It can provide experimental and theoretical basis for further study on conductive electromagnetic noise of pantograph-catenary system.
