Abstract

Continuous monitoring of power grid aimed at assuring compliance of power quality indexes to standard requirements, calls for a wide range of instruments, each devoted to a different measurement. Metrological confirmation of the whole set of devices and instruments turns out to be a complex task – because of the variety of characteristics to be tested – that requires time to be com-pleted which eventually determines high costs, not to mention that during confirmation activities in-struments cannot be used. The purpose of the laboratory presented is to provide a complete set of con-firmation services through local branches distributed over the territory. A central laboratory plans and supervises activities which are then delegated to peripheral labs employing travelling standards to perform confirmation directly at client’s side thus reducing sensibly times of off-line operations. Experimental results from two different kind of measurements that require fast acquisition in one case and accurate acquisition in the other are reported as an example of the wide range of possible applications.
