Research of parallel placed submarine cable route detection method

According to the impact of the submarine high voltage cable with a three-phase cable placed close to the route on submarine cable location detection, this paper clarifies basic detection methods for the submarine cable route, and also analyzes the distribution law of magnetic induction signal in the state of the adjacent multi-cable. Specific implemented measures of submarine cable location detection are summarized at the end of this paper. In addition, it solves the magnetic signal interference problem in the state of the adjacent multi-cable.
