<p>PURPOSE:To obtain a voltage detector being miniature size and stable in motion by connecting a wire conductor part circumferentially surrounded by an inductive substance part and electrode plate with a photo voltage sensor respectively, and still more connecting a light source and photoelectric converter through an optical fiber. CONSTITUTION:A dielectric part 22 is provided so as to surround circumference by a wire conductor part 21 as an axis. Next, an electrode plate 23 is provided through the dielectric part 22 in opposition to the wire conductor part 21. And, the wire conductor part 21 and the electrode 23 are connected through a metal tool 24, electrode terminal 25 respectively with voltage impressing terminals 28, 27 of a photo voltage sensor 26 applying Pockels effect etc. Further, this optical voltage sensor 26 is connected through optical fibers 29, 31 with a light source 30 and light receiving part 32 respectively. By this method, the miniature size voltage detector simple in constitution, less in variation due to time elapse and stable in motion is obtained.</p> |
