Influence of fault arc characteristics on the accuracy of digital fault locators.

Influence of fault arc characteristics on the accuracy of digital fault locators.

This paper proposes a time domain model of a fault locator with special reference to fault are nonlinearities by applying the MODELS language of the EMTP. It has been found that an impedance relay type locator is significantly influenced by the fault arc nonlinearities, while the current diversion r...
