摘要
An atmospheric electrode is charged by electrostatic induction from a leader stroke which is associated with lightning formation. The electrode is earthed through a varistor which becomes conductive when the value of the tension associated to the electric field at ground exceeds a pre- determined value. In this way, a destructive return stroke, which usually follows a leader stroke during lightning formation, is avoided.
