The consumption of electricity exists thanks to a séries of agents that par-ticipate throughout a spécial process. The process starts with the génération of electricity, which is then distributed to the final consumer. Throughout thèse phases, electricity undergoes a séries of altérations that can greatly affect it. The electricity companies in charge of distrib-uting electrical energy are responsible for guaranteeing that the voltage supplied meets a séries of parameters, which will dépend on the géographie area. There are différent loads connected to the distribution network and, in many cases, loads can vary as technology evolves, thus affecting the stability of the distribution network as a whole.
Industries use increasingly more sofisti-cated processes with a greater number of control, automation and régulation éléments, allowing companies to exécute such processes automatically and be more compétitive. In gênerai, said loads are very sensitive to voltage variations, which can lead to faulty performance and critical problems in processes. On the other hand, more and more companies are starting to invest in the meas-urement and control of the quality of the electricity supplied, in order to avoid a séries of costs that are usually associated to production processes.
This means that the costs associated to a lack in the continuity of the supply and those related to an insufficient supply quality must be controlled. It is very important to supervise the correct opération of the installation and equipment

connected to it, including the correct management of energy to avoid unnec-essary consumption excesses.
The globalization of markets has also led the différent players involved in the energy génération, transport and consumption processes to communicate on the same terms to face the new future challenges required to optimise distribution networks and electricity installations. Therefore, current régulations pay spécial attention to the use of éléments that take measurements in accordance with a séries of spécifie criteria, to facili-tate the interprétation of ail information gathered.
The intake of measurements from différent points of the distribution network requires the use of equipment that can guarantee the total précision of the measurement taken and a proven ro-bustness, since the equipment will have to face complex environments and situations. We are talking about equipment of référence for electricity companies throughout the worid in very différent environments and distribution networks. At the same time, companies are operat-ing in increasingly global environments, forcing them to be more compétitive and to optimise their processes. Therefore, the electrical altérations affecting productive processes in companies must be analysed and studied with the pur-pose of improving and protecting installations against such altérations.
