Abstract
A vacuum-capacitor-type instrument voltage transformer () is equipped with a main capacitor () and an insulating tube () that accommodates the main capacitor (). A voltage dividing capacitor () is connected to the main capacitor () in series. The main capacitor () is equipped with a plurality of vacuum capacitors () to () that are connected in series. A high-voltage-side electrode () is provided on a high-voltage side of the insulating tube (), and a ground-side electrode () is provided on its low-voltage side. The high-voltage-side electrode () is equipped with a high-voltage shield (). Electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor ()) disposed on the high-voltage side is set to be greater than electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor ()) disposed on the low-voltage side.
