Isolating spark gaps have been designed to isolate electrical system components, which under normal operating conditions are not connected together. If lightning strikes cause a potential increase in one of the electrical system components, the isolating spark gap guarantees a conductive connection and therefore Equipotential bonding. Isolating Spark Gaps are used when conductive installation components situated in explosion-hazard areas cannot be connected directly with each other. The spark gaps with low spark over voltage are especially efficient for isolated installation components with little insulation resistance.
