Testing of Electrical Energy Meters Subject to Realistic Distorted Voltages and Currents
This paper presents a study on revenue active electrical energy meters. The huge installation along the distribution network of these devices made them a key element for energy billing, but also for monitoring the grid status. Hence, it is evident that the relevance of guaranteeing a trusty metering...

The operation of the meters is regulated by standards harmonized with the European Directive 2014/32/EU (known as MID).
