The utility model discloses a transformer load remote monitoring device and a transformer load remote monitoring system. Transformer substation metering device, the system comprises an acquisition device, a single-chip microcomputer module, a GSM module, a display screen and a key module. The acquisition device is connected with the transformer substation metering device and is used for reading metering data; the single-chip microcomputer module is connected with the acquisition device and used for analyzing the metering acquisition information. The single-chip microcomputer module is furtherconnected with a GSM module and a display screen and used for controlling the GSM module to send early warning information and displaying the set maximum charge and minimum charge information of transformer metering data early warning through the display screen. When a load suddenly drops or suddenly increases or is not in a normal value range, the GSM module sends load alarm information to a mobile phone of an equipment owner, so that the equipment owner can know the operation condition of the transformer at the first time, possible problems are researched and judged, and the reliability of power utilization of a user is ensured.
