があった。A conventional insulator type current transformer is constructed as described above, and has terminals (7
), (8), (9), and (IQ) are attached to the side wall (51) of the head tank (5), so when current flows through the line, eddy current loss occurs on the side wall (51). In order to reduce the eddy current loss, the entire side wall (51) is made of a non-magnetic material such as stainless steel. There was a problem that it required materials and was expensive.

2) Since the top cover (52) (which is generally flat) has a smaller area than the side wall (51), even if the top cover (52) is made of a non-magnetic material, it requires a smaller amount than if it is formed with sleeves, and the cost is reduced. In addition, the connecting pieces (15) and (16) can be made into flat plate-like pieces with a simple structure, and when they are made into flat plate-like pieces like this, they can be manufactured with good workability and at low cost. In the above embodiment, the cross-sectional shape of the head tank (5) is rectangular, but it may also be circular, oval, or other shape. Further, the number of primary windings is also limited to two, but may be three or more.
