SEMOD168232-4 v2
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.
The distance protection function is designed to meet basic requirements for
application on transmission and sub transmission lines (solid earthed systems)
although it also can be used on distribution levels.
