Simple distance protection scheme
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 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 …
