Abstract

A protective system for an electrical inductive apparatus having windings, such as a transformer, and having a capacitance in circuit relationship in series with one of the windings, in which an air gap device is connected for arcing through said capacitance, said air gap device comprising a pair of electrodes arranged so that a predetermined air gap remains between them, and a pair of magnets arranged to provide a magnetic field through said air gap, thereby from said air gap the break occurs that conducts the electricity in the form of an arc when the voltage through said capacitance reaches a predetermined magnitude, and said arc is extinguished by the action of said magnetic field after the discharge of said capacitance.
