Description
Summary:According to Finnish legislation, at least 80 % of the energy meters have to be remotely readable and provide hourly based energy data by the end of 2013. In April 2011 Tampere University of Technology (TUT) in co-operation with Finnish Energy Industry conducted a questionnaire to Finnish distribution network operators (DNOs) to map the installation status of the remotely readable meters, the communication technologies used in the meters and the interference problems experienced so far, related to, especially, PLC (power line communication) systems. The questionnaire dealt with both the interference caused by customer apparatus to PLC and vice versa. On-site measurements to study common customer apparatus disturbing the PLC were also conducted in 2012 in the networks of a few DNOs. Most common disturbance sources were frequency converters and switch mode power supplies. The measurements indicate that in addition to the lack of emission standards below 150 kHz the aging of customer equipment may be a relevant cause of interference problems.
