Abstract
The paper describes a digital computer programme for the protection of a three-phase transmission line. This programme detects the presence of a disturbance, classifies the fault into one of six fault types and, using a method of impedance calculation described in an earlier paper, determines the modulus and phase of the impedance of the faulted line. Accuracy of calculation and reliability of detection are determined from fault data for a model transmission line.Keywords
