Abstract
This invention provides a high voltage transient protection unit comprising a recoverable spark gap, an L-C filter, a voltage variable resistor and provision for specified ground connection of these elements; and a method of protecting electrical equipment from damage due to a high voltage transient comprising directing any transient above a predetermined minimum voltage level through a recoverable spark gap to a first grounding circuit; delaying said transient for a sufficient time to allow said spark gap to fire and filtering out through a separate grounding circuit that portion of a transient below said predetermined minimum level and above a predetermined maximum voltage level.
