Cao Min, Wang Zheng, Zhang Jiye. Method and apparatus design for feed cable voltage standing wave ratio fault location[J]. 2014,(4):34-35. DOI: 10.13756/j.gtxyj.2014.04.011.
This paper introduces a Frequency Domain Reflectometry(FDR)-based method and apparatus design for feed cable Voltage Standing Wave Ratio(VSWR)fault location.By sending frequency sweeping test signals at specific bands
it transfers the power signal value overlaid by the sending power value
the faulty feed cable reflected signal and the incident signal vector through the communication interface to the computer and its software calculates the distance of the feed cable fault points on the basis of these two power values
thus achieving the accurate location of the feed cable fault.
