摘要： An optical fiber-containing insulator comprises an insulator body (1) having a through hole (2) provided in its central portion and extending along an axial direction thereof, an optical fiber core wire (3) passing through the through hole, and an insulating material (4) filled between an inner peripheral surface of the through hole and the optical fiber core wire. To avoid tension on the optical fiber, means e.g. a taper (2a) are provided for preventing the filled insulating material from axially protruding out of the insulator body even at high temperatures. To prevent the fiber (3) touching the body (1), there are means for holding the optical fiber core wire at the central portion of the through hole of the insulator body.

摘要： A system for detecting a fault occurred within a substation and judging a location of the fault including optical current sensors each having a Faraday element arranged on a top of an insulator post of a bus disconnecting switch, a magnetic core arranged to surround a terminal plate of the disconnecting switch to generate a magnetic field corresponding to a current passing through the terminal plate, a laser diode for emitting a laser light beam, an optical fiber for guiding the laser beam to the Faraday element, a photodiode, and an optical fiber for guiding the laser beam transmitted through the Faraday element to the photodiode. The photodiode supplies a signal representing the current passing through the terminal plate to a fault location judging circuit in which the fault location within the substation is judged from the signals from the photodiodes.

摘要： In a system for transmitting an electrical power supply by means of an over-head power transmission line supported by power transmission towers, a fault such as a short-circuit fault and a ground fault is detected by providing optical current sensors (1) having opto-magnetic elements (3) and opto-electric field elements (20) on respective conductors (7) of the transmission line to detect a fault current and fault voltage on the basis of the Faraday's effect and Pockel's effect. Light beams passing through the elements are modulated by the magnetic fields induced by the currents passing through the conductors and the voltages on the conductors, and thus include information about the current and voltage. There is further provided a circuit for calculating a distance to a fault point in accordance with the detected current, voltage and a phase difference therebetween and a known impedance of the power transmission line. The thus calculated distance to the fault point is displayed on a display device which is arranged at the power transmission tower or the sub-station.
