In complex railway lines or hub areas,the"T-connection"mode is sometimes adopted for traction network.Based on the study of"T-connection"traction network circuit,a correction method of calculating the fault distance by using the principle of transverse current ratio is put forward for fault condition of"T-connection"full parallel AT power supply traction.
