<br> In this embodiment, the local server 1 issues a command to the coordinator 2 which executes the command by sending a corresponding knowledge packet wirelessly to the good meters 3 by a radio frequency (RF) link, e.g. ZigBee? which will or may not assist an industry commonplace such as IEEE 802.14.5. Then the smart meters three send an applicable response back to the coordinator 2 by the identical RF hyperlink. In another embodiment, the native server 1 is related to the coordinator 2 wirelessly. The facility utilization will be accessed for instance by displaying net pages using any device that's connected to the local server or the internet. The average power dissipated in resistive hundreds, e.g. family appliances, may be calculated as the product of root-mean-squares of current and voltage averaged over a time interval. The ability usage will also be analyzed to allow system control, e.g. minimize off the ability if needed.<br>
<br> The first terminal of a small shunt resistor RS 7 is related in collection with the recent line of power line pair 6 which is a high voltage portion 100
