Canadian national power quality survey

An increasing number of polluting electrical and electronic loads are being connected to today's electrical distribution systems. With this comes the potential for increased customer complaints about 'alleged' power supply quality problems affecting the performance of 'sensitive' electronic equipment. The Canadian Electrical Association (CEA) is taking a proactive approach to this problem and has started a two year survey of power quality across Canada. The authors present a detailed discussion of what data is being captured for this survey, new techniques being used to analyze the data, and how the results are being displayed to show a comprehensive, high-level summary of the power quality measured at each sample site. The authors also discuss the technical requirements for the power line monitors that were chosen, and the rationale behind the monitor thresholds being used for this survey. A sample survey site report is also shown and discussed.<
