Abstract
Un indicador de falla interna para un dispositivo electrico se acciona por un incremento subito en la presion como ocurre cuando una falla de aislamiento crea un arco electrico. El calor librado en el arco se transforma en el volumen circundante provocando sobrecalentamiento localizado, vaporizacion y descomposicion del material aislante. La variacion de presion resultante mueve un diafragma. El movimiento del diafragma libera un embolo accionado con muelle de un barril que se extiende a traves del alojamiento del dispositivo electrico. Antes de la activacion, el embolo se mantiene una "posicion armada" por la espiga de retencion. En el accionamiento, el embolo se empuja por el muelle hasta que sobresale del alojamiento para proporcionar una senal visual de la falla interna. Se puede integrar una valvula de alivio de presion con el indicador de falla interna.
