The measurement of short-duration impulse voltages

Abstract
A description is given of a very-small-impulse voltage divider which is insulated by compressed gas. The divider was designed for the measurement of steep-front impulse waves, and its errors have been evaluated by the step-response method, using a pressurized sphere gap. It was then used for measuring the volt-time curve of a sphere gap, and the results have been compared with those obtained by others.
