Abstract: Electrical energy is the most widely used and most important direct or indirect energy source in various industries such as industrial and agricultural production and national defense science experiments. The transmission distance of electric energy can reach hundreds of kilometers or even thousands of kilometers. Long-distance transmission lines are non-ideal lines, that is, the resistance of the transmission line cannot be ignored. Therefore, the line power loss in the long-distance transmission process is inevitable, and the understanding of some problems in the preparation of some physical basic teaching materials and physics teaching is one-sided. Based on the transformation and conservation laws of energy, based on the working principle of the transformer and the actual load matching of the transmission system, the basic research on the line loss power in long-distance transmission is given, and the traditional understanding of the line loss power in long-distance transmission is pointed out or corrected. It is not comprehensive or even wrong.Abstract: Electrical energy is the most widely used and most important direct or indirect energy source in various industries such as industrial and agricultural production and national defense science experiments.
