Abstract
This paper describes apparatus used for the measurement of breakdown voltages between electrodes in vacuum with potentials up to the order of 500 kv. The use of a direct voltage of this magnitude required special shielding to limit electrical stresses in the lead‐in bushing of the vacuum tank. The source of power was an electrostatic belt generator with a corona‐leak voltage control. Voltage was measured with a xylene alcohol high resistance voltmeter. Incidental work with stand‐off insulators in vacuum is described. The results of a series of breakdown measurements are shown with a curve.Keywords
