  • Patent number: 5083233
    Abstract: A protective device for an insulating flange of a high voltage transmission system comprises a varistor unit in combination with a spark gap. The varistor unit is clamped between a pair of radially extending stub plates connecting the unit in shunt with the insulating flange. The spark gap is defined by a pair of spark electrodes mounted on the stub plates radially outwardly of the varistor unit so that the latter shields the insulating flange from molten metal and heat generated at the spark gap should the varistor unit fail.
