Application of Electromagnetic Technology in Fault Location of Submarine Cables
Due to complex operating environment of submarine cables,fault location often suffers from poor accuracy and low efficiency.Based on the principle of electromagnetic induction,combined with a construction case of submarine cable location for offshore wind farm fan collectors in China,magnetic field waveform characteristics of the faulty submarine cable were studied,and the difference of magnetic field waveform under different electrical wiring conditions was analyzed.At the same time,measurement data of global positioning system(GPS)was coupled to achieve accurate fault location.Results showed that electromagnetic technology could effectively realize the accurate fault location of submarine cables,which could provide a feasible case for similar fault location,and was of great significance for the implementation and promotion of related technologies in the future.
