An electric energy distribution systems protection microprocessor based relay

Abstract

This work depicts the development of an electrical energy distribution systems protection microprocessor based digital relay, commercialization viable, first in its kind in Mexico. It is an overcurrent relay with independent protection elements such as ground, phases, negative sequence, low frequency protection, recloser, directional elements, fault locator, oscilography and other auxiliary elements that constitute a first level protection system achieved by Mexican engineers.
