International power quality standards are put in perspective with requirement specifications for observatories. This contribution describes themotivation, the underlying mechanisms that lead to issues, comments on the challenge in power systems engineering, proposes the instrumentation and installation, and interprets the first results. Experimental results clearly motivate the need for further measurement campaigns, as power-quality-related problems are common.
