Patent ID: 7755873

Claim:
A surge protector device of the spark gap lightning arrestor kind, the device comprising: a) a first spark gap; b) a first pre-trigger system electrically connected to the first spark gap in such a manner as to enable an arc to be struck therein; c) a control device electrically connected to the first pre-trigger system in such a manner as to activate it; d) at least one second spark gap connected in parallel with the first spark gap; and, e) a second pre-trigger system electrically connected to the second spark gap and connected in parallel with the first pre-trigger system, in such a manner that the control device activates the first and second pre-trigger systems simultaneously so as to trigger the first and second spark gaps simultaneously, wherein each pre-trigger system is an electronic system comprising a trigger electrode and a transformer having a primary winding, and wherein the primary windings of the transformers corresponding respectively to the first and second pre-trigger systems are connected in parallel.
