Real-time Intranet-controlled virtual instrument multiple-circuit power monitoring

The virtual instrument (VI) based power metering manifold (PMM), monitoring multiple branch circuits on a common distribution panel, is enhanced by the client-server interactive network architecture. The Intranet-controlled power monitoring system integrates control, measurement, and communication, while it still maintains economy by eliminating the extra network construction and hardware investment. Moreover, the multicast Web application enables the power metering results to be accessed by multiple users for a variety of applications in a real-time manner.
