Q 4: What analysis tools are available to utilities to assist in evaluating distance relay performance on series compensated applications prior to the purchase or choice of a particular relay type? Steadystate fault simulations as PSSE and CAPE used for calculating relay settings are not suitable EMTP studies insufficient due to the manufacturers secrets The only tool is simulator tests Svenska Kraftnät use simulator tests to evaluate new distance relays for series compensated lines Leif Koppari
