PTB-News 1.2023 – Real-time capable controlling and monitoring systems are necessary when it comes to ensuring the stability of future electrical distribution and transmission grids. Also required are meters that can accurately and with high temporal resolution measure energy flows that are relevant to energy billing. In the future, the measuring equipment needed for this purpose may be based on digital, i.e., sampled-value (SV) technologies whose high-voltage sensors and downstream measuring electronics have to be very accurately synchronized. For verifying SV-based electrical energy meters, PTB has developed a measuring setup based on an SV protocol generator that serves as a calibrator.
