Abstract

Single-line fault diagnosis in delta-delta connected distribution systems suffers due to the low fault currents associated with such faults. Simulation tests on this type of system reveals that rule based decision support can be used for such diagnosis. This paper describes the development of rules for single-line fault diagnosis utilizing simulation test results. The key parameters used are the voltage magnitude of each phase at the busbar and the currents on the feeders including their sequence components
