Abstract
INDICADOR DE ELEVACION DE CORRIENTE (10) QUE TIENE UN ELEMENTO FERROMAGNETICO (12) COLOCADO ALREDEDOR DE UN CONDUCTOR (15), ESTANDO LOS EXTREMOS DEL ELEMENTO (12) PROXIMOS Y MIRANDOSE ENTRE SI, DE TAL FORMA QUE SE ATRAEN ENTRE SI CON UNA FUERZA DADA AL PASAR LA CORRIENTE A TRAVES DEL CONDUCTOR (15). CUANDO LA FUERZA EXCEDE UN LIMITE DADO, SE CREA UNA SEÑAL PARA FACILITAR LA LOCALIZACION DEL PUNTO DONDE LA ELEVACION DE CORRIENTE SE HA PRODUCIDO. EL ELEMENTO PUEDE ESTAR MONTADO A MODO DE MUELLE PARA ABRIRSE, Y LA SEÑAL PUEDE SER PROPORCIONADA POR EL ELEMENTO AL SER LIBERADO POR LA ELEVACION DE CORRIENTE, DE TAL FORMA QUE EL ELEMENTO SE CAE DESDE EL CONDUCTOR. EL CONDUCTOR PUEDE SER UN CABLE DE ANCLAJE DE UN AISLANTE O VIGA DE TORRE PARA UNA LINEA DE TRANSMISION DE ENERGIA.
