| Abstract: | A new method of on line measuring AC resistance at the joint of high voltage transmission line and its practice of soft ware and hardware are described in this paper. On the basis of electromagnetic theory,the induced electromotive force superimposed on the resistance voltage drop is removed from the measuring loop by the use of a coil.This device is small in size,light in weight. The test results show that it has high accuracy and is easy to operate. |
