Abstract :
This paper presents a new algorithm for faulty phase selection in transmission lines. The algorithm is based on a limited soft processing of the 3-phase and the zero-component current phasors. Current phasors are determined by using a pair of short length data window filters giving orthogonal outputs phasor components. The soft processing means here that, generally, the operations like min and max are used rather than multiplication or summation of two or more arguments.
