Development and testing of an experimental power system fault demonstrator

In this paper a laboratory demonstrator for the study of power system faults is described. The facility has been developed in order to experimentally investigate a number of fault location and power system protection technologies developed by the authors and their colleagues at higher power levels and with more representative system parameters than has previously been possible. In addition to describing the facility itself, this paper also describes the validation of a previously studied method using the new demonstrator.
