What Is Trigatron Gap?

A trigatron is a type of triggerable spark gap

switch designed for high current and high voltage (usually 10–100 kV and 20–100 kA, though devices in the mega-ampere range exist as well). It has very simple construction and in many cases is the lowest cost high energy switching option. ... A trigatron has three electrodes.

What is a triggered spark gap?

A midplane triggered spark gap has a trigger electrode in the form of disk halfway between the two main electrodes. ... This is like halving the distance between the main electrodes and doubles the field strength between the trigger disk and the positive main electrode.

Why is control tripping necessary?

In large impulse generators, the spark gaps are generally sphere gaps or gaps formed by hemispherical electrodes. The gaps are arranged such that sparking of one gap results in automatic sparking of other gaps as overvoltage is impressed on the other. ...
