Abstract

In this paper, we propose a novel method to detect the time for voltage to reciprocate the cable by using sinusoidal voltage. It can be detected by changing the frequency of the sinusoidal voltage applied to the cable and measuring the amplitude of the combined wave. The proposed method makes it possible to realize a highly accurate cable length measurement. A measuring device using the proposed detection method has been manufactured. As a result of measuring the cable length, measurement with an error of 0.1% or less of the cable length is performed.
