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： The object of the invention is to provide technique and an apparatus for precisely measuring high frequency current that flows in a transmission line of a small impedance load circuit. A current waveform can be measured in wide bandwidth (at high-time resolution) and at high sensitivity without processing DUT (nondestructive) and without having an effect of the impedance of the apparatus (noninvasive) by installing a magnetooptical device in a magnetic field generated based upon current that flows in the transmission line, applying a bias magnetic field to the magnetooptical device by a magnetic field generator, making polarized light incident under the control of a position so that detection sensitivity is maximum and detecting the variation of polarization included in reflected light from the magnetooptical device.

摘要： Provided is a technique for mass-producing a conductor to which is fixed a current detection head that detects the value of current flowing in the conductor, and in which the relationship between the detection value and the current value is stabilized. The head comprises a lens, a magneto-optical element, a conductor, and a fixing member, and the lens, the magneto-optical element, and the conductor are respectively fixed to the fixing member. An optical system is formed using the current detection head such that light is guided through the lens to the magneto-optical element, and light affected by a magneto-optical effect due to the magneto-optical element is guided to the lens. All of the members contributing to current detection are fixed to the fixing member, and therefore the relative positional relationships of all the members contributing to current detection are uniquely determined, enabling conductors with little variation in current detection characteristics to be mass-produced. A shape for determining the positional relationship between the fixing member and the conductor may be formed therebetween in advance, and the positioned current detection head and conductor may be fixed to obtain the conductor.
