Transformer operation monitoring and resistor grounding protection system

The invention provides a transformer operation monitoring and resistor grounding protection system, and relates to the technical field of transformer protection. Comprising a monitoring terminal, a display terminal and a transmission terminal, and the monitoring terminal is connected with a transformer and used for monitoring the operation state of the transformer and transmitting the operation state of the transformer to the display terminal; the display terminal is connected with the monitoring terminal and is used for receiving the transformer operation state data transmitted by the monitoring terminal; the transmission terminal is connected with the display terminal in a wireless communication mode, and the data of the operation state of the transformer monitored by the monitoring terminal can be sent to the transmission terminal; when the transformer has a grounding fault, resonance energy can be absorbed, non-metallic grounding intermittent arc can be eliminated, and other fault identification, fault da
