摘要
In this paper a method is described for the estimation of the pressure inside vacuum circuit breakers which have been in operation during several years. The method is applicable for measurements in the field and uses only elctrical measurement techniques. The vacuum circuit breakers switches off a 10 A DC current; are voltage pulses are measured and represented in a hystogram. The shape of the hystogram is discriminative for pressures below or above 10(-4) mbar.
