摘要： An improved voltage transformer for use in a gas insulated or liquid insulated high voltage switching installation enclosed within a metal encapsulation and carrying several conductors, in which each conductor is surrounded by a tube which is conductive at least on its surface which faces the conductor with the tubes connected to each other through attachment means which attach them in an insulated manner to the metal encapsulation. The resulting arrangement causes each tube together with the conductor within it to form a high potential capacitor which can be coupled in series with a low potential capacitor to form a voltage divider with the voltage taken off the low potential capacitor and used to provide an indication of the voltage present on the conductor. Tubes which are plastic with conductive coatings and metal tubes are disclosed with the tubes fastened to at least one support disk of insulating material which is then attached to the metal encapsulation.

摘要： A voltage measuring device for use with an encapsulated, high-voltage switching installation including an inner conductor within a grounded metallic outer tube. The measuring device includes means for widening the outer tube, thereby providing a space for locating certain portions of the measuring device. Positioned in the space formed by the widening means is an auxiliary electrode means, insulated from the outer tube, which forms a capacitor with the inner conductor. Measuring means and servo-indicating means are connected in various ways to the capacitor formed by the auxiliary electrode means and the inner conductor. These measuring means respond to variations in the electrical characteristics of the capacitor thus formed to thereby give an indication of the voltage of the inner conductor.

摘要： A voltage transformer for a completely insulated, metal-clad, high-voltage installation includes an electrode of extended surface area which is arranged inside the metal outer tube of the high-voltage installation. This electrode and the high-voltage conductor of the installation conjointly define the highpotential capacitor of a capacitive voltage divider. The dielectric of the high-potential capacitor is an insulating member which carries the extended-area electrode. The insulating member carries, in addition, the low-potential capacitor of the capacitive voltage divider. An amplifier, followed by a load, is connected to the low-potential capacitor.

摘要： A sensor for sensing stress in a ferromagnetic material includes a non-magnetic substrate. The substrate has a first surface and a second surface opposite the first surface. A first coil is attached to or formed on the first surface of the substrate. The first coil is configured to induce a magnetic flux in the ferromagnetic material being driven by an alternating current (AC) signal. At least one second coil is attached to or formed on the first surface of the substrate. The at least one second coil is spaced from the first coil. In addition, the second coil is configured to detect changes in the magnetic flux induced in the ferromagnetic material.

摘要： The present invention provides a current sensing module for a current sensor and a method for manufacturing the current sensing module. The current sensing module includes a spacer layer including a through hole and being annular in shape, and a circuit board electrically connected to the current sensor and includes at least two structural layers. The two structural layers cover the spacer layer and each of the structural layers includes at least one metal wire layer insulated from the spacer layer. The two metal wire layers are conducted to form a loop coil surrounding the spacer layer. When a wire is located in the through hole, an external power supply power to the circuit board, such that the circuit board has a detection state in which a sensing current is outputted due to magnetic induction generated by the loop coil during the wire is electrically conducted.
