<p>PURPOSE:To prevent the generation of corrosion due to the contact between different kinds of metal and to perform highly reliable measurement by simplifying a structure and facilitating mounting by receiving a coil in a metal tube composed of the same material quality as the surface of a transmission line conductor in an insulated state. CONSTITUTION:A transmission line current sensor 1 is mounted to a transmission line 2 as shown by a drawing. In this case, the transmission line current sensor 1 performed in a spiral shape can be mounted to the outer periphery of the transmission line 2 in a close contact state and it not detached because it is self-supported by the elasticity of a metal tube 14 receiving a coil 13. The transmission line 2 is ACSR (steel core aluminum stranded wire) employed in a transmission line widely and generally and, since the material quality of the line 2 being in contact with the transmission line current sensor 1 is made of the same aluminum as the metal tube 14, the corrosion due to the contact with a different kind of a metal is not generated.</p> |
