These changes in the network will normally impose morestringent demands on the fault clearing equipment in order to maintain anunchanged or increased security level of the power system.The distance protection function is designed to meet basic requirements forapplication on transmission and sub transmission lines (solid earthed systems)although it also can be used on distribution levels.1MRK 506 369-UEN B Section 8Impedance protectionLine distance protection REL670 2.2 IEC 147Application manual
