Abstract

EN UN SISTEMA PARA MEDIDA REMOTA DE PROTECCION DE MASA, CONSTA DE UN DISPOSITIVO DE MEDIDA DE MASA CENTRALIZADA (1), UN SELECTOR DE LINEA (2) Y ACTUADORES CONTROLADOS DE FORMA REMOTA (3) LOCALIZADOS CERCA DE LA REGION EN LA QUE LA MEDIDA SE REQUIERE, DICHA MEDIDA DE RESISTENCIA DE MASA SE REALIZA DE TAL MODO QUE EL PUNTO DE MEDIDA ESTA MUY DISTANTE DE LAS MASAS DE REFERENCIA, DE MODO QUE POR ESTE MEDIO LAS CAPAS MAS PROFUNDAS DEL SUELO ESTAN INVOLUCRADAS EN LA MEDIDA, QUE PUEDE CONSIDERARSE QUE ESTA A POTENCIAL CONSTANTE.
