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.
