Abstract
Equipment operating at high voltage which is subject to damaging voltage breakdown at relatively high altitudes and therefore relatively low pressures has a pressure sensitive switch such as a spark gap included in the high voltage circuit in shunting relationship. At lower altitudes no voltage breakdown occurs across the spark gap and the high voltage circuit operates normally.At high altitude voltage breakdown occurs across the spark gap shunting potentially harmful voltages from the high voltage equipment.
