The effect of the definition used in measuring partial discharge inception voltages

Abstract

At present, several definitions of partial discharge inception voltage (PDIV) have been advanced. To establish the value of each of these definitions, four practical electrical insulating fluids are selected, and their PDIV is determined according to three of these different specifications. The results suggest that the use of PDIV as a quality criterion generally is not warranted. The significance of these findings is discussed. >
