Claims

[Scope of utility model registration request]

In an insulator-type current generator that induces a secondary current in the secondary coil by electromagnetic induction that interlinks the primary coil and the secondary coil, insulation is provided between the input-side conductor and the output-side conductor of the primary coil. An insulator type current transformer characterized in that a structural part is constructed as an annular insulator whose outer peripheral surface is formed into a wave shape.
