WebbDistance protection is a mature protection mainly used in transmission systems . It is based on the observation that the protected line impedance is proportional to its length: monitoring changes in the impedance (e.g. by measuring locally voltage and current) thus enables the identification of a fault without any communication device. WebbThe distance protection function blocks are independent of each other for each zone. Each function block comprises a number of different functional inputs and outputs, which are …

WebbDistance-based feeder protection schemes accommodate instantaneous trip elements and have fixed zones of protection, independent of changing system conditions. For example, should the source behind the relay change, then fault currents at any location on the feeder will change as a result. WebbAs a result of being an unconditional trip, intertripping equipment is usually designed with greater security safeguards than protection signalling, to minimise the risk of incorrect …

WebbThe method of distance protection scheme used was a three-stepped distance protection scheme in which the transmission line was segmented into three zones; 70%, 90% and 100% and the discrimination between each zone was 200ms in order to ensure proper coordination of the protective devices.
