<p>PROBLEM TO BE SOLVED: To solve the problem that conventionally a large storage case is required for attachment of a coil-type current transformer onto a bushing part, and that an attaching method simplified in structure is required, when the transformer is attached to the bushing part. SOLUTION: By inserting a main circuit conductor 13 into a bushing 12 led out from electric power equipment, attaching an umbrella-shaped shield cover 24 comprising a curved surface part, having a prescribed curvature of cross-sectional shape to a shield 20 in the outer circumferential side of the bushing 12, and attaching an optical fiber 27 inside the shield cover, an optical fiber type current transformer 23 is attached easily, using the existing shield 20 without requiring a newly space.</p> |
