Electromagnetic pulse protective properties in transient suppressors consisting of gas discharge tubes and filters

The effect of the components of a transient suppressor on the protective function, of the device were studied. Measurements show that the operation of the gas tubes requires low inductive connectors. An injected pulse with a rate of rise of 20 A/nsec lights the tubes within less than 2 nsec. The filter consists of an inductor and a Zener diode. The residual voltage is attenuated by the inductor, while the high frequency components pass due to stray capacitance. The Zener diode clamps the voltage only at the low frequency part. Calculations for a model theoretical circuit are presented.
