Abstract
Disclosed is an improved impulse circuit for delivering, from an electrical charge in a capacitor, an electrostatic spark discharge across an air gap to equipment under test. The circuit includes a gas gap in series combination between said air gap and the high energy side of the capacitor. Also included is a divider network, including resistors connected across the gaps so as to apportion voltages across the gaps upon application of the charge from the capacitor to the resistors so that initial electrical conduction through a first of the gaps leads to a spark discharge across the second gap, and the major flow of current from the capacitor passes first through the second gap and then through said already conducting first gap to produce said spark discharge across the first gap with current waveforms defined primarily by the firing characteristics of the second gap under conditions of overvoltage of the second gap.
