Abstract: Two methods, voltage detecting method and compensated voltage detecting method, are proposed for detecting the permanent faults and transient faults of multiple line traction network. The effectiveness and sensitivity of these two methods are verified by computer simulation. The simulation results show that both of the two detecting methods are effective, and the compensated voltage detecting method is more sensitive.
