Abstract

A study of the voltage coefficient of precise compressed-gas capacitors is described. A series of measuring methods based on the formula for calculating the voltage coefficient is presented: measuring the variations of capacitance when the capacitor is tilted in various directions to a specific angle; measuring the variations in capacitance when the capacitor is tilted in a specific direction to various angles; and measuring the variations in the coordinates of the electrodes when these electrodes are subjected to various mechanical forces, etc. These methods were used to test a 350 kV, 50 pF capacitor, and its voltage coefficient was found to be less than one part in a million from 0 kV up to 350 kV
