<p><P>PROBLEM TO BE SOLVED: To provide a noncontact power transmission line sensor which is hardly influenced by an output due to a power transmission line of another phase, the weather or the like, whose adjustment accompanying the installation of the sensor can be reduced and whose mounting workability is satisfactory. <P>SOLUTION: The power transmission line sensor is provided with a sensor in which a voltage sensor and a current sensor are integrated, thereby, it is made to be attached easily to a power transmission line steel tower. The line sensor is provided with a correction circuit, and it can obtain an automatically corrected signal value. Consequently, a large accuracy is not required when the sensor is attached, the mounting operation of the line sensor can be shortened, and a burden on an operator can be reduced. By limiting the arrangement and installation position of the sensor in advance to a definite range, the sensor can be arranged and installed easily in a position in which an influence due to other lines is small, and a more precise signal value can be obtained. <P>COPYRIGHT: (C)2003,JPO</p> |
