This paper describes a preliminary experience with the installation and use of a no-gap power quality meter network along a distribution grid in the North of Spain. No-gap power quality meters record all cycles of voltage and current waveform for all the monitored channels. This approach extends the analysis further than the classical approach provided by other power quality meters that records only survey data and events triggered according predefined rules. A comparison with the classical approach is discussed and the results of a two year power quality survey are also provided.
