<p>PROBLEM TO BE SOLVED: To eliminate necessity of treating an energized part for measurement by simplifying the fixing and removing of sensor part to the part of the energized part for measurement (bus). SOLUTION: A forward path 4F and a return path 4R are bent in U-shape. The U-shaped space 4U formed by the forward path 4F and the return path 4R is set as a position to arrange a bus 1. To the return path 4R, a pipe 5 with a high permeability is placed around to magnetically shield. Thus simply by arranging a sensor from one side of the bus 1 fixing and removal of the sensor part to the bus 1 become very easy. Furthermore, it is unnecessary to cut the bus 1, so there is no fear of damaging the reliability of the bus 1, such as heating and imperfect contact, and it becomes economical.</p> |
