As the amount of EV charging stations is growing and micro grids applications are expanding, the reliability and accuracy of the energy meter, on which the payment is based, is getting more important. In this presentation we discuss the various challenging aspects of the verification of such meters that use pulse intervals as a means to count the energy. To measure this correctly according the standard requirements, a special measurement method in combination with the right probing technique is required. ZES ZIMMER and Danisense have developed a measurement method that overcomes this challenge by carefully selecting the measurement strategy and current probes using fluxgate closed loop technology.
