Abstract
Equipo multifrecuencia detector del estado de los electrodos en los hornos de arco eléctrico para obtener valores reales de la situación interna de un electrodo donde se están produciendo cambios de fase, realizándose mediante un equipo externo al mismo, al que se le introduce una pequeña señal eléctrica de baja potencia y frecuencia variable a través de un elemento buen conductor y que al variar la frecuencia de dicha corriente eléctrica, permitirá conocer cual es la situación del electrodo a sus distintas alturas, incluso por debajo de las placas de cocción.
