Abstract: In an optical current transformer in which the Faraday rotation of light in a waveguide (2) enclosing the current is measured, the waveguide (2) is designed as an integrated-optics single-mode waveguide embedded in a substrate (1).Further elements of the measuring device, such as polarizers (13), mirrors (11) and Y couplers (12, 14), may likewise advantageously be integrated into the substrate (1).The integration leads to a sensor element (SE) which can be produced in a simple manner and is to a large extent insensitive to environmental influences such as temperature fluctuations and vibrations.

Abstract: A fiber-optical current transformer including a sensor coil, operated in reflection mode, with a sensor fiber (5) for detecting a current utilizing of the Faraday effect. A light source (1) couples light into an incoming first HB fiber (2a). At the end of the first HB fiber (2a), a fiber-optical polarizer (4) is preferably located which ensures a direction of polarization in parallel with a given birefringence axis of the first HB fiber (2a). A Y splitter (3) couples, on the one hand, the supplied light of the first HB fiber (2a) into the sensor fiber (5) and, on the other hand, the light coming from the sensor fiber (5) into an outgoing second HB fiber (2b). The second HB fiber (2b) is rotated with its birefringence axes by 45.degree. with respect to the birefringence axes of the first HB fiber (2a).

Abstract: In a gas-insulated switchgear having an isolated-phase bus, a current-carrying bus (2) with a given external radius R.sub.1 is arranged coaxially in a cylindrical enclosure with a given external radius R.sub.2, the voltage of the current carrying bus is measured using optical fiber voltage transducers. For this purpose, at least three identical piezoelectric sensor elements are provided. They are arranged essentially at a distance corresponding to the internal radius R.sub.2 from an axis of the current carrying bus in the enclosure at identical angular distances. The sensor elements are preferably accommodated together with an optical fiber curent transducer in a metal ring that can be inserted into the enclosure.

Abstract: The invention relates to a system suitable for a remote interrogation of passive transponders using chirp signals for interrogation. The transponder preferably has an encoding unit (11), a calibrating unit (12) and a measuring unit (13) each with a plurality of parallel channels (11.1 to 11.5, 12.1 and 13.1 to 13.2). The encoding unit and the calibrating unit are preferably jointly incorporated with a common delay line (14) on the same SAW chip. The interrogation signals received in the transponder via an antenna (10) are delayed characteristically and code-specifically, in particular in the encoding and calibrating unit. Decoding in the interrogation station is preformed by discrete Fourier transformation of the response signal and subsequent evaluation of the spectrum. To correct general disturbing influences on the delay of the response signal, said signal is calibrated using a single calibrating component in the response signal. Calibration occurs by appropriate shift of the spectrum of the stored response signal. For partial correction of individual disturbing influences on the delay of the response signal components, the calibrated response signal undergoes additional correction. If further measuring response signals similar to the identifying and calibrating response signals are produced then they can, for example, be used to measure temperature by appropriate evaluation of the digitally stored response signal. The preferred combination of measuring and encoding unit enables each transponder to be calibrated individually, and consequently, for example, measurement of the absolute temperature.
