Abstract

RELE PARA SISTEMAS TRIFASICOS. EL RELE PUEDE SER DE LOS TIPOS DE PROTECCION DE RELACION, O DE DESEQUILIBRIO DE PORCENTAJE. DETECTA CONDUCTORES DE FASE ABIERTA EN CIRCUITOS DE DISTRIBUCION ELECTRICA, ASI COMO FALLAS DE FASE UNICA A TIERRA SIN CONSIDERACION A LA IMPEDANCIA DE FALLA. PROPORCIONA UNA CANTIDAD DE OPERACION QUE RESPONDE A CORRIENTE DE SECUENCIA DE CERO, Y UNA CANTIDAD DE RESTRICCION QUE RESPONDE A LA DIFERENCIA ENTRE LA CORRIENTE DE FASE EQUILIBRADA ANTES DE FALLA Y LA CORRIENTE DE SECUENCIA DE CERO. ESTA DISPOSICION DE PAR DE TORSION DE RESTRICCION POSIBILITA QUE EL RELE OPERE SOBRE EL DESEQUILIBRIO DE RELACION VERDADERO, SIN CONSIDERACION A LA CARGA.
