A spark gap is an electrical device whose spark gap breaks through at a certain value of the applied voltage, thereby limiting the overvoltage in the installation. The main element of the spark gap is the spark gap. The volt-second characteristic of this interval lies below the volt-second characteristic of the protected equipment. When an overvoltage occurs, the gap breaks through earlier than the insulation of the protected equipment.
