Low-Cost Smart Power Sensors with Condition Monitoring Capabilities

The Department of Energy has identified a need for low-cost, wireless, three-phase, true power sensors for commercial and industrial applications at a target cost of $20 per meter. The proposed work addresses the three largest cost drivers of existing power measurement solutions: (1) hardware cost, (2) communications interfacing cost, both hardware and software, and (3) installation complexity including configuring communications. InGreenium will combine digital signal processing techniques with enterprise software methods in a novel architecture that reduces cost and improves measurement accuracy. The proposed work will demonstrate key algorithms on modular sensor hardware and will then demonstrate that the algorithms can be migrated to an integrated, application-specific platform. InGreeniums solution also provides condition monitoring to enable predictive maintenance of electrical motors and other loads.
