Abstract
Sistema de protección para faltas de alta impedancia en líneas de distribución eléctrica. El sistema está previsto para detectar las incidencias posibles que se producen fase-fase y fase-tierra, proporcionando una protección incluso cuando los niveles de impedancia alcanzados sean elevados. El sistema, aplicable a una subestación de distribución con su correspondiente barra distribución (1) de la que se derivan las líneas de distribución (2), incorporando cada una de éstas un interruptor (8), comprende un generador de señales (4) que son convenientemente moduladas y codificadas para que sean detectadas por un sensor (6) previsto en cada línea (2) y asociado a un equipo de protección (7) conectado al correspondiente interruptor (8) de cada línea (2), con la particularidad de que las señales procedentes del generador (4) son aplicadas a la barra de distribución (1) mediante un dispositivo adaptador (5), todo ello de manera tal que el dispositivo de protección (7), con la información proveniente del generador (4) y la intensidad medida por el sensor (6) establecerá la variación de la impedancia de la línea (2) operando ante determinados cambios de la misma.Protection system for high impedance faults in electrical distribution lines. The system is designed to detect possible incidents that occur phase-phase and phase-earth, providing protection even when the impedance levels reached are high. The system, applicable to a distribution substation with its corresponding distribution bar (1) from which the distribution lines (2) are derived, each incorporating a switch (8), comprises a signal generator (4) that they are conveniently modulated and coded to be detected by a sensor (6) provided in each line (2) and associated with a protective equipment (7) connected to the corresponding switch (8) of each line (2), with the particularity of that the signals from the generator (4) are applied to the busbar (1) by means of an adapter device (5), all in such a way that the protection device (7), with the information from the generator (4) and the intensity measured by the sensor (6) will establish the variation of the impedance of the line (2) operating before certain changes of the same.
