Abstract
A system and method for measuring, monitoring and controlling electrical power directed through one or more electricity directing devices is provided. The one or more electricity directing devices includes electrical sockets supplying power to one or more devices. The system includes a potential transformer configured to receive AC voltage directed through a socket and further configured to relay the voltage to a processing device. The system further includes a current sensor configured to sense current drawn from the socket and further configured to relay the current to the processing device. A microcontroller is adapted to receive analog or digital values of voltage and current corresponding to AC voltage and AC current. The microcontroller then measures values of voltage and current, calculate electrical power consumed and generate a control signal. The control signal activates a switching device operationally connected to the socket and switches power flow through the socket.
