Document Type and Number:
Japanese Patent JPS5694925
Kind Code:
A
Abstract:
A method of and apparatus for detecting a ground on an electric furnace comprising connecting an electrode, which is located in the furnace, to ground potential and sensing the current flowing from the electrode to ground. The method and apparatus may also include comparing the sensed current with a first and second reference signal and actuating an appropriate alarm when the sensed current is greater than the first reference signal or less than the second reference signal and interrupting the electrical power to the furnace when the sensed current is greater than the first reference signal.
