Abstract

PROCESO DE PROTECCION SELECTIVA CONTRA LOS DEFECTOS A LA TIERRA, CARACTERIZADO EN QUE SE MIDE PERMANENTEMENTE, EN CADA SALIDA, LA POTENCIA HOMOPOLAR INSTANTANEA SOBRE UNA BANDA ANCHA DE FRECUENCIAS, EN QUE SE LA COMPARA A UN PRIMER UMBRAL DE DEFECTO PERMANENTE, Y A UN SEGUNDO UMBRAL SUPERIOR AL PRIMERO, Y EN CASO DE REBASARLA DURANTE UN PERIODO DE LA TENSION, EN QUE SE ENGENDRA UNA SEÑALIZACION DE DEFECTO TRANSITORIO, Y EN QUE SE COMPARA LA TENSION HOMOPOLAR A UN UMBRAL INFERIOR A LA TENSION NOMINAL Y EN CASO DE SOBREPASAR DURANTE UNA DURACION PREDETERMINADA QUE PRECEDE EL REBASAMIENTO DEL SEGUNDO UMBRAL, LAS SEÑALIZACIONES INSTANTANEAS DE TODAS LAS SALIDAS SON INHIBIDAS DURANTE UN TIEMPO DE INHIBICION REGULADO.
