TIMER-ELECTRIC METER WITH GSM COMMUNICATION CHANNEL Russian patent published in 2023 - IPC G01R11/42 G01R19/00 

FIELD: measuring devices.

SUBSTANCE: timer-electric meter with a GSM communication channel for remote measurements of the parameters of the operating modes of the electrical network with data transmission to a remote server via cellular networks contains a microcontroller, an indication and alarm unit, three current sensors, three voltage sensors, and an additional current sensor that measures current in the neutral conductor of the studied power line, and a built-in GSM modem that sends data to a remote server via cellular networks, the outputs and inputs of which are connected to the inputs and outputs of the microcontroller. In addition, the device contains a real-time clock unit that binds data to astronomical time, a data recording unit, an indication and alarm unit, the outputs of which are connected to the microcontroller inputs.

EFFECT: mobile measurement of the parameters of the operating modes of the electrical network under study and implementation of remote control of the network operation.
