Parallel series-compensated lines appear as very important links between energy generation and consumption regions. Such lines exhibit the advantages relevant for both the parallel arrangement and for the series capacitor compensation itself [1, 2]. However, they are considered as extremely difficult for protective relaying as well as for locating faults for inspection and repair purposes [1-3].
Series Capacitors (SCs) installed in the lines are equipped - for
overvoltage protection - with nonlinear Metal-Oxide
Varistors (MOVs).
