Isolated satellite surge current detecting method

The invention discloses an isolated satellite surge current detecting method which comprises the following steps of 1, clamping a satellite positive bus-bar cable bundle by means of a Hall current clamp; 2, connecting the output end of the current clamp with a PC through a signal high-speed sampling device; 3, programming upper computer software by the PC end, and processing and storing a received current signal; and 4, through a man-machine interaction interface, performing comparative analysis, curve real-time displaying, alarming and the like on a surge current value by the PC end. The isolated satellite surge current detecting method has advantages of simple operation, comprehensive, accurate and effective data. The man-machine interaction interface is utilized for realizing higher visuality of a detecting result. A Hall sensor is utilized for performing isolated sampling on the current signal of the satellite positive bus-bar, thereby ensuring isolation between a satellite and ground, and realizing high
