Abstract
Conventional fault location schemes do not take loads and their variable 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 novel method for such lines is proposed. The fault distance is obtained by solving an implicit equation. Single-phase-to-ground, phase-to-phase, and three-phase-to-ground faults are treated. The effect of the scheme is illustrated by simulated faults
