内容記述 |
Recently, the fiber optical current sensors based on the Faraday effect have been developed and applied to power distribution systems. However, there are some requirements for putting the sensors on practical power distribution lines, that is, it is desired that they are of compact form and light weight, and also operate in high sensitivity and accuracy in a wide temperature range, etc. It is well known that garnets, especially bismuth-substituted rare-earth iron garnets (hereafter call as RIG), have the Verdet constants of higher sensitivity than other Faraday materials such as Bi12GeO20, while the constants of the sensitive RIG have a temperature dependency.
In this work, first, the same three sets of optical current sensor systems consisting of a RIG films were manufactured. Second, in room laboratory, the sensitivity and temperature dependency of each sensor system were examined by measuring the output voltages of the detecting unit corresponding to the currents flowed in 6kV three-phase power distribution lines. As a result, it was found that the deviation in the linearity of output voltages to applied currents of each sensor was within ±1.2% and these sensors had a high accuracy less than ±1.3% in a tempereture range from -20 to 80℃, and these values are satisfactory ones from the practical viewpoint. Moreover, as a field test, the three sets of sensor systems individually were set without ring core on the actual three-phase power distribution lines at hot-line conditions, the normal load line currents in the three-phase power distribution lines were measured for a long time by using these three set of sensor systems together with the conventional current transformers. As a result, it was found that the optical current sensor system used in this work had successfully good characterstics in practical use. Also, the harmonic current in high voltage distribution lines were measured with these optical current sensor systems, and they were analyzed by a computer. |
