Smart Building energy disaggregation Submeter with LEM Split-core CT ATO

Industrial companies, factories, multi-tenant commercial and residential building owners install submetering equipment for the purpose of real-time in-house metering. This allows for accurate allocation of costs, calculation of internal billing and enables the implementation of new energy efficiency measures. Buildings typically consume energy to provide heat, air conditioning, lighting, display lighting, signage and other electrical ...

IoT remote energy monitoring using LEM Split-Core CT (ATO) following the IEC 61869-2 Smart Grid standard

IoT Remote Energy Monitoring for the Smart Grid IoT is perfectly suited for smart grid roll-out, thanks to the long range requirements and the small data size needed for transmission. Using narrow-band RF, the standard for long-range communication, an innovative remote energy monitoring solution is now possible. The solution consists of wireless energy meters for ...

Distribution Overhead Line Monitoring with LEM’s ART Rogowski coil

New line current sensors allow utilities to monitor their overhead distribution lines to maximize their capacity and prevent clearance violations thus improving reliability and efficiency of the MV Distribution Grid. The High Voltage transmission grid is already highly automated and monitored through SCADA and Energy Management Systems. In contrast, the Medium-Low Voltage distribution grid has ...

Smart Transformer condition monitoring with Smart Meter and Rogowski Coils

  Smart Grid for the City The intelligent electricity network (smart grid) is the backbone of every smart city, since it: Informs “prosumers” (proactive consumers or producers of energy) about their energy usage and enables them to make decisions about how, when to use, store or even resell electricity, as with solar panels on roof ...
