Normal power monitors use an inductance meter that clamps around a power conductor and measures the field. The down-side of these clamp-on meters is that you need to separate the power lines to measure one at a time. So the described device would need to have 2 sensors, one for each 120V (for a house) line, or one for each phase of a 3 phase commercial installation, then each sensor would wirelessly transmit to a processor which would hopefully display the useage of each leg. This would be very helpful as many residential and commercial electrical systems are significantly unablanced. Most large power users monitor their power useage by using Current Transformers (CTs) which drive the meter rather than passing the entire current through the meter itself. However those CTs typically do not communicate with any other monitoring devices so cannot provide much information beyond bulk useage. Is the described device really new technology?
