Abstract

See full text

A vacuum-capacitor-type instrument voltage transformer (1) is equipped with a main capacitor (2) and an insulating tube (3) that accommodates the main capacitor (2). A voltage dividing capacitor (4) is connected to the main capacitor (2) in series. The main capacitor (2) is equipped with a plurality of vacuum capacitors (2a) to (2c) that are connected in series. A high-voltage-side electrode (6) is provided on a high-voltage side of the insulating tube (3), and a ground-side electrode (7) is provided on its low-voltage side. The high-voltage-side electrode (6) is equipped with a high-voltage shield (8). Electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor (2a)) disposed on the high-voltage side is set to be greater than electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor (2b)) disposed on the low-voltage side.
