Abstract
An energy monitoring system which in preferred embodiments employs at least one nodal junction receiving and creating data by analog to digital conversion from a plurality of local node sensors. Data accumulated by the nodal junction is used for analysis of wave patterns to detect anomalies in the local electrical network and/or loads connected to the local electrical network. Anomalies can be detected in various ways, including: comparison of data with historical data acquired from the local node sensors; comparison of data with known wave pattern profiles for similar loads; and comparison of data with data acquired from local node sensors at other locations. Thus, the accumulation of data in the system of the invention provides the ability to perform comparative analysis to a baseline or standard, and also the ability to perform comparative analysis at an enterprise level across different target locations.
