Preliminary Investigation of Proposed Pulse Method for Measuring Ionization

Source

A laboratory with a background of ionization measurement by the radio influence method reports on a preliminary investigation of ionization measurement by the pulse method. The investigation is confined to two specimens: a high-voltage terminal bushing and an artificial specimen comprised of capacitors and a spark gap. Three types of detection circuit (that is the element across which the oscilloscope signal is developed) are tried and the results are presented. A detection circuit which will be set in oscillation by the pulse is recommended whenever a 60-cycle sweep is used on the oscilloscope. In cases of multiple voids and multiple pulses per void per half cycle, the pulse measuring technique becomes complicated and the radio influence method is preferred.
