Utilising innovative techniques and wireless communications, the system accurately measures real power without batteries or needing an electrician to install.
About
Many systems that purport to measure power, in fact only consider apparent power. So they are completely inaccurate and misleading in any cases where there is micro-generation or where the loads are non-resistive! With the proliferation of switched mode power supplies and the like, that is the majority of installations. This innovation measures real power (as well as the power factor), which is what standard domestic electricity meters report. Further it is non-invasive and does not need to be installed by an electrician. The sensor is powered by energy harvesting and so needs no batteries or maintenance. Communication between the sensor and the system hub is wireless, so no cabling is needed.
Key Benefits
Accurate real-time measurement of real power (and power factor, etc.). As well as power measurement the system enables real-time control of devices/loads to optimise performance. For example, instead of exporting surplus micro-generation power, it can be diverted to heat water, charge batteries, etc. Non-invasive installation, not requiring an electrician. The energy harvesting sensor uses no batteries and hence is maintenance free. Wireless communication between the sensor and the system hub means that there is no cabling required. The system hub can connect to wider network(s) wirelessly or via cabling. The wireless communications use an open international standard which is certified woldwide. The transmission frequency used is sub-GHz and so has better range and penetration properties suited to buildings.
Applications
Any requiring real power measurement and/or related control such as diverting surplus generated power for local uses instead of export to the national grid. Circuit/consumption monitoring across multiple spaces. Independent Electricity meter checking/validation. Other sensors (typically energy harvesting and batteryless), such as environmental monitoring (temperature, humidity, air , etc.), door/window status and occupancy can also be integrated into a complete system. As well as enabling the implementation of sustainable environmentally friendly and efficient systems, strategies such as demand-side and frequency responsive control can be employed. Data can readily be made available for display by smart phone apps, tablets, etc. as well as being saved into a database.
