Abstract
The invention relates to a magnetic-information feedback method used for a cable terminal. The steps of the method are as follows: (1) converting cable electric field information into magnetic field information; (2) acquiring and then storing the magnetic field information; (3) carrying out comparison and analysis of data information on the stored magnetic field information and judging whether the acquired magnetic field information exceeds a magnetic field information rated value; (4) recording magnetic field information which exceeds the rated value and prompting through an alarm. The electrical field information is converted into the magnetic field information for acquisition and thus the electrical field information of a cable terminal of a substation field is monitored in a real-time manner so that no matter for preliminary test or daily use, the method has better applicability to cable terminals of different voltage grades.
