Claims

[Scope of utility model registration request]

In the capacitor-type voltage transformer, the capacitor body is housed in two or more stacked insulator tubes via a metal connection member, and the metal connection between the metal connection member and the capacitor body is A capacitor-type instrument transformer, characterized in that a part adjacent to a member is electrically connected via a high impedance element.
