SURVEYS - why?

• to investigate power quality related problems
• to quantify levels of distortion for G5/4-1 compliance assessment
• to establish distortion levels prior to load changes
• as part of power quality management philosophy
• to establish accurate loading levels on multiple supplies

o- how?

• our surveys are non-disruptive in 99% of cases - no isolation required
• 'snapshot' harmonic measurements at a time of typical loading, or..
• a 7 day harmonic survey, or..
• tailored to meet the circumstances
• our easy-to-read reports include recommendations where necessary
• can be at very short notice if needed
• feel free to ask for advice - we have over 20 years experience
