Abstract The operating characteristics are forwarded for the 33kV ring network power supply system of Guangzhou metro line 4. Its problems of the time differential for overcurrent protection are illustrated. The time differential of overcurrent protection is discussed. Combined with the actual situation of equipment, resetting and coordination calculate the time differential of overcurrent protection, to further ensure the normal and steady operation of 33kV power supply system of Guangzhou metro line 4.
