Abstract
ESKOM has relied primarily on impedance-based measurement protection relays for the protection of EHV transmission lines. One of the main disadvantages of a distance relays is the limited fault resistance measurement capability. There are currently more than 20 relay types applied as transmission line protection on the ESKOM´s transmission network with the most common types of characteristic being mho and polygonal characteristics.
