Programa para verificar la calibracion de un rele de proteccion por impedancia
(Polytechnic University of Puerto Rico, 1992-12)
This article describes the preparation of a testing file to verify the calibration of an impedance protection relay using the Mastertest program. With this work we present an alternative to the ones now used for relay ...
Fallas de alta impedancia en los sistemas de distribución eléctrica
(Polytechnic University of Puerto Rico, 1992-06)
Most of the time, a fault in an electrical power system presents a much higher current than the current that flows in the system during. normal conditions. This fault current is harmful for the components of the system ...
