End-to-end testing transmission line protection schemes and double-ended fault locators

Abstract

This paper explains how to test double-ended fault locators for high voltage overhead transmission lines. There are many similarities to testing high speed communication assisted tripping schemes (HSCATS) however there are some important differences which are covered here in detail. Note that double-ended fault location is coming into vogue now and these tests can be performed in unison while testing the HSCATS.
