Abstract
Aiming at reaching the best quality in terms of supplying and services, some utilities are using more and more automation and instrumentation devices in its networks. Thus, in a new scenario, voltage sags are available from some additional measurements along the feeder by means of power quality or voltage measurement devices. In this work, a fault location algorithm, which uses voltage sag measurements, for primary distribution feeders is proposed. Preliminary tests performed on large-scale practical feeders using a generic load modeling show that the proposed algorithm is robust and suitable for carrying out fault location with improved accuracy.
