    Abstract: PROBLEM TO BE SOLVED: To provide a sensor for electric or magnetic field without deficiencies of conventional technique. SOLUTION: A sensor head 2 can be bent in the domain of sensor fiber 3. Friction depressant 7 is contained in a capillary tube 6 to reduce frictional force between the sensor fiber 3 and the capillary tube 6. The frictional depressant 7 is oil or dry lubricant. The capillary tube 6 is enveloped with a capillary tube sheath 8. The sensor head 2 makes it possible to measure current in conductor of large cross-section by its easy mounting on conductor, in addition to measurement independent of temperature.

    Abstract: A method is described for producing a fiberoptic waveguide with a basic segment (11) and a phase shift segment (12), the basic segment (11) and phase shift segment (12) having fiber cores (K) of the same form and the fiber cores being aligned at a defined angle (.alpha.) to one another. In the method, use is made of an optical fiber (1) having a fiber core (K) of the abovenamed form, which fiber is twisted at least approximately by the abovenamed defined angle (.alpha.) and held fixed in this torsional position. Subsequently, a stress-relief zone (13) is heated inside the twisted fiber (1) until the torsion is released inside the stress-relief zone (13) and the basic segment (11) is produced on one side of the stress-relief zone (13) and the phase shift segment (12) is produced on the other side. In this case, the fixing of the torsional position is maintained until after solidification of the stress-relief zone (13).

    Abstract: The spacers (5) are electrically conductive and contact adjacent sensor sections (2). The voltage sensor (1) high tension section is qualified for open air use. This derives from the high tension dielectric and protective screen (against weather) surrounding the assembly of sensor- and spacer sections. The sensor is made of individual sections, and a continuous sensor fiber (4a). In each section, a given length of optical fiber is fastened to the body (3) such that its length is varied only by E-field components parallel to the sensor axis. The amplification factor of each section is proportional to its length, in correspondence with the piezoelectrically-induced length variation of the fiber. Sensor sections and spacers are cylindrical and aligned along the sensor axis. Between sensors and spacers, there are conductive flexible holders (6). The holders include inner- and control electrodes, with spring sections. Inner electrodes bond and interlock with the end surfaces of sensor elements. Control electrodes are fastened onto the inner electrodes. Spring sections connect the inner electrodes to adjacent spacer sections. The dielectric is an elastomer or insulating fluid. The protecting screen is an elastomer with additional support insulator. The silicone body may have an additional fiberglass-reinforced plastic insulating rod. A version using a dielectric of transformer- or silicone oil is also described. The connection contacts (1a) of the high tension section comprise flanges, a hanger and a corona- and/or voltage control ring. An earthing and anchoring cable is included.
