<p>PROBLEM TO BE SOLVED: To efficiently detect an electromagnetic wave accompanying partial discharge generated in a high voltage vessel in a flexible structure form the surface of an insulation spacer and to easily realize shielding of outside noise. SOLUTION: A highly flexible external sensor for detecting that the high frequency electromagnetic wave generated by accompaniment of the partial discharge leaks from a spacer is provided, has stable detection sensitivity by combining a cushion body and a shield belt therewith as shown in figure 2, and the influence of the outside noise is suppressed. Furthermore, it can cope with always attaching specifications by combining a flexible metal cover. It can be stably attached to the surface of an arbitrary sized spacer, and the influence of the outside noise can be suppressed. Kinds of combined parts are not enough, and the economical external sensor can be provided.</p> |
