Remote reading and data management system for kWh-meters with power quality monitoring

A new remote reading system for kWh-meters was developed because new requirements have emerged. The amount of data to be collected and processed is increasing with the number of remote readable meters. Data from the meter reading systems must be accessible for the invoicing and energy management systems in an easy and standardized way. Deregulation of the energy markets brings new actors that need energy consumption measurement data. New applications like monitoring the power quality and network state are included in the kWh-meter and its reading system. However, the reliability and confidentiality of the measurements should not be violated
