Purpose
ELSA is part of the service that Energiföretagen Sverige offers within the framework of the Swedish National Cluster Sampling of Electricity Meters. With the ELSA system, you can register and follow up the quality assurance of household electricity meters
Method
Virtually all household electricity meters in Sweden are registered in ELSA. The information about the electricity meters in the database is used to select a number of electricity meters for control in a nationwide random survey. The selected meters are checked by control bodies approved by Swedac. The results of the surveys are used to approve batches of electricity meters for six years at a time, which can then be used by customers until a cluster sampling shows that the authorities' requirements for function and measurement accuracy are no longer met.
More information on the Swedish National Cluster Sampling of Electricity Meters, timetables, instructions and plans for future cluster samplings can be found at Energiföretagen Sverige.
