Abstract
This paper has proposed a time domain model of a fault locator with special reference to fault are nonlinearities by applying the MODELS language of t he EMTP. It has been found that an impedance relay type locator is signific antly influenced by the fault are nonlinearities, while the current diversi on ratio method is not influenced, This validates the advantage of the curr ent diversion approach over the impedance approach.
