As a result of increasing law regulations, energy subscribers will be provided more freedom to choose between tariffs and utilities, optimizing their energy costs. However, with an increase of renewable energy generation, local utilities require a more efficient way to monitor the energy consumed on a subscriber level, in order to adjust the conventional electrical energy generation. The utility’s business model – pre-paid vs. after-paid – will mainly be driven by local consumption and payment habits. Consequently, future electricity meters will require reliable bidirectional communication paths to address these needs. The solutions that will be chosen will depend on local circumstances and will be either wired or wireless. Although the solution presented will address a 3-ph shunt E-Meter application, the same principles of operation are applicable to current transformer and Rogowski-coil based sensing approaches, with the intrinsic isolation provided by the inductive approach being the differentiator as compared to the shunt approach.
