Abstract
Conventional fault location schemes do not take loads and their valuable impedance behavior into account. This leads to unacceptable errors in the case of radial transmission lines with loads, commonly found at the 120 Kv and lower levels. A new method for such lines is proposed in this paper. The fault distance is obtained by the solving an implicit equation. Single phase to ground, phase to phase and three phase to ground faults are treated. The effect of the new scheme is illustrated by simulated faults.
