A spark gap for use in the power supply of medium voltage and low voltage networks, wherein two rotationally symmetric electrodes are arranged in a housing and an arc space is provided between the two electrodes for the arc which is formed in the event of a spark-over and its follow-on current. The two electrodes are arranged in the direction of the longitudinal center axis of the spark gap one behind the other and at a distance from each other. A disk of an electrically insulating material is positioned perpendicularly of the longitudinal center axis so as to electrically separate the two electrodes from each other. The insulating disk has an opening adapted to the hollow cylindrical inner space forming the spark-over place for the arc. The arc space includes a rotationally symmetric arc chamber arranged concentrically with the longitudinal center axis for the follow-on current. The arc chamber is positioned between the two electrodes. The electrically active length of the arc chamber can be selected differently while the outside dimensions of the spark gap are maintained.

Spark gap

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.

Spark gap arrangement

An arrangement for protecting devices connected to transmission lines against excess or interfering voltages resulting from lightning strokes and the action of EMP or EMI, which arrangement includes a circuit board carrying connectors for establishing connections with such transmission lines and with the devices, lightning protection chokes connected in series between the transmission line connectors and the device connectors, first excess voltage arresters connected between the transmission line connectors and the chokes for effecting coarse overvoltage protection for the devices, second excess voltage arresters connected between the device connectors and the chokes for effecting fine overvoltage protection for the devices, and a network with frequency dependent behavior connected between the device connectors and the second excess voltage arresters, and a ground conductor constituted by a large-area metal plate oriented parallel to the circuit board.
