Abstract

PURPOSE:To reduce the number of sensors and maintain higher safety, by providing a separable connector coupling portion on a casing wiring portion and providing a casing with a penetrated portion which is shielded on an outside lead-out portion and sealed up to prevent internal gas from leaking. CONSTITUTION:A sensor cable 4 is a coaxial shielded cable which is less affected by an external noise and another noise due to the deformation of the cable itself. The sensor cable extends to the penetrated portion 7 of a casing 6 through an inside connector coupling portion 5. This coupling portion is made of a coaxial connector. In the case of the dielectric strength test of a stator winding or a similar case, the cable 4 is disconnected at the coupling portion 5 and enough dielectric strength is set to insulate the casing 6 from sensors 3, 3'. The shielded section 8 of the led-out portion of the cable 4 is directly coupled to the grounded casing so that a voltage produced by electrostatic induction is released to the ground. This results in maintaining higher safety.
