Application

Sub-transmission networks are being extended and often become more and more complex,
consisting of a high number of multi-circuit and/or multi terminal lines of very different
lengths. These changes in the network will normally impose more stringent demands on the
fault clearing equipment in order to maintain an unchanged or increased security level of the
power system.
