Analysers of quality of electrical supply: for the detection of perturbations in the electrical network
The analysers of quality of supply QNA fulfil with the international norms more demanding. At present, the norm IEC-61000-4-30 specify how this type of equipment have to realise the measures of all a group of parameters. Inside this norm, differentiate 2 classes. In the first place, the class To reserves to those equipment of more precision and more provision, which have to fulfil of form very rigorous with a methodology of measure, and have to have a high precision in all the parameters that measure. Those equipment certified with the precision class To of this norm, are used like elements patterns and can be used arrived the case to resolve any type of dispute. The range of analysers of quality QNA series 400 fulfil with these demanding norms, being in installations very diverse the patterns of measure used.
