Abstract

A spark gap arrangement capable of handling lightning includes a first spark gap with a relatively high-resistance insulating layer having a relatively short spark-over path, and at least one second spark gap which, compared to the first spark gap, has a relatively low-resistance insulating layer with a relatively long spark-over path, the second spark gap being electrically connected in series to the first spark gap.
