Abstract
[Task] The present invention aims to provide a vacuum capacitor instrument voltage transformer by which current and voltage can be much precisely measured. [Means for achieving task] The means is so made that a main capacitor portionand a voltage dividing capacitor portionare installed in a earthed vacuum vessel, a main ground circuitis provided through which a leak current Iflows from an outer surface of the primary line-path side vacuum vessel to the earth E, and a voltage dividing ground circuitis provided through which a leak current Iflows to the earth E through a voltage dividing insulating cylindrical memberthat is disposed between an earthed portion and each of the main capacitor portion and the voltage dividing capacitor portion.
