WebbDistance protection is used for the protection of extra high voltage transmission and sub-transmission The major advantage of distance protection is that it would do the fault coverage of the circuit independent of the variations in the source voltage It would provide primary and backup protection 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.
