Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, to a wireless communication transformer winding deformation frequency response method detection operation system and method. Background technique [0002] The power transformer is the key core equipment of the power system, and the equipment installed in the power grid system is huge, and its operation reliability is directly related to the power supply security of the power system. However, in recent years, transformer winding deformation faults have occurred frequently, ranking first among transformer faults. According to incomplete statistics, transformer winding deformation faults account for 33.8% of all transformer faults. Frequent deformation faults of transformer windings have led to great concerns about equipment reliability, especially as the scale of power systems becomes larger and higher, the level of short-circuit current in the system increase...
