Abstract The module of TramWame ground-level power supply system and the principle of safety negative is described. Since the traction power supply substation adopts the bilateral power supply mode, the power supply negative and safety negative is connected to the same negative busbar in the negative cabinet of the substation, then the power supply negative current will flow into the safety negative which cause the trip of the action of the production device and broken of the normal operation of the system. The unidirectional conduction device prevents the power supply current from following into the safety negative to ensure safe and reliable operation of the system.
