description	The invention discloses an accurate sensing system for a power supply state of a digital special transformer. The accurate sensing system comprises a passive wireless mutual inductor, a power supply state sensing unit and a master station server, when an on-site transformer is started, the low-voltage side of the transformer generates voltage and current data, the voltage and current data are monitored through a passive wireless mutual inductor and uploaded to a power supply state sensing unit in a 433MHz wireless communication mode, and the power supply state sensing unit uploads the voltage and current data to a master station server through wireless communication. Therefore, the data change condition of the passing voltage and current is judged at the PC end or the APP end, and whether the transformer runs or not is judged. The special transformer power supply state sensing unit is developed, and on the basis of not changing an existing special transformer district structure, low power consumption, low cos
