1. A circuit monitoring arrangement which monitors power distributed to a plurality of powered equipment, wherein a power-related waveform passes from a non-residential loadcenter to each of the powered equipment through a power line, and zero-crossings of the waveform define the cycles of the waveform, the arrangement comprising:

  • a sensor, disposed adjacent the power line and between the loadcenter and at least one of said power equipment, for sensing power parameters associated with the power-related waveform;

    detection means, responsive to said sensor, for sensing the waveform;

    sampling means, responsive to said detection means, for sampling the power-related waveform for a predetermined number of sample points;

    generation means, responsive to said sampling means, for generating data representative of said sample points and transmitting said data in a form which represents said power-related waveform; and

    a computer, remotely coupled to said generation means, for evaluating said generated data at a remote location, such that the computer receives the generated data to monitor the power passing from the loadcenter to the powered equipment.
