Abstract: Electromagnetic waves generated by partial discharge occurring when gas- insulated apparatus fails are detected by using a compact, wide band and high sensitivity antenna. Electromagnetic waves produced by partial discharge are detected over a wide range with a high sensitivity by a circular antenna receiver (4) which comprises a pair of semi-circular discs combined on a plane inside the metal vessel (3) of the gas- insulated apparatus. The detected signal is measured by a measuring instrument (10) through a coaxial enclosed terminal (7) and a coaxial cable (8). Since the area of the semi-circular antenna unit is large, the capacitance between the antenna unit and a potential measuring unit can be large, so that the high sensitivity potential measurement can be also performed.

CONSTITUTION: A device for attaching a strain gauge to a sensing element by an adhesive agent hardening at a high temperature, is formed in the shape of cover for surrounding a column of the sensing element and includes a screw coupling part mounted on an outer surface, and a heating coil wound on an inner part, wherein the heating coil includes heating parts(2) of which one ends are connected to a heat controller of a control part and a compression part(3) composed of compression clamps(30) having an opened side and mounted with a cylindrical pad having a curvature equal to the sensing element at a length-variable shaft.
