摘要

This paper analyzes the principles and advantages of the current cable guard alarm technology. Given the limitations and defects of the low-voltage power cable guard alarm mechanism at present, we adopt the impedance measurement of alternating sampling algorithm and a combination of power line carrier, and propose a new mechanism for an integrated cable guard alarm system. The mechanism use fuzzy logic to judge the quality of the current, and calculate the protected setting value. It gives out the reliable alarm signal through the electric current dynamic analyses when the cable is cut off and stolen.
