A voltage-only method for estimating the location of transmission faults

This dissertation develops, and illustrates with actual data, a new voltage-only based fault location procedure that incorporates the system impedance matrices into the problem so that as few as three or four voltage recording devices can estimate the fault location over a wide area. This procedure can quickly help pinpoint the fault and complement other available information normally used to manually locate the fault. The second approach takes advantage of the capabilities of microprocessor relays on distribution feeders to reflect their voltage sag measurements back to the transmission system for use with the above algorithm.
