Abstract
A more sensitive and accurate circuit has been devised and tested for showing integrated corona charge transfer per cycle in insulation samples. The method can be used as a very accurate and more rapid quality-control measurement of degree of impregnation or residual voids in apparatus insulation. A rather precise measurement of the fraction of gas space to solid in insulation structures can be obtained from this technique. The estimate of internal voids obtained from this technique is believed to be more accurate than that obtained from highvoltage Schering bridge measurements, with which it can be correlated.Keywords
