Conclusion References Abstract--This paper proposes a new scheme for backup protection of transmission lines with a limited number of phasor measurement units (PMUs). In the presented methodology, the PMUs are located (or installed) in accordance with a scheme allowing all faults to be observable. The network is divided into a few zones with 1, 2 or 3 transmission lines. Following this, the nearest bus to the fault location, named as the faulted bus, is selected through the voltage data measured by PMUs. A faulted area including the suspected zones, the zones connected to the faulted bus, is then identified. The faulted zone is subsequently recognized by using the phase deviation between the positive-(negative-) sequence voltage of the faulted bus and the positive-(negative-) sequence of the input current to the suspected zones. The faulted line is finally detected based on the type of the faulted zone and c
