Alessandro Giuseppe Antonio Anastasio Volta

With his “Voltaic Pile” (the first electric battery) Volta provided the first source of continuous current. The volt, a unit of the electromotive force that drives current, was named in his honour in 1881.

Vision Power Quality is an application which transforms measurement data about voltage quality into useful information. This is achieved by means of smart processing, aggregation and visualisation. The application uses classification to report the PQ levels in a uniform and comparable way.

Power quality
Our modern society is more and more sensitive to power quality problems. Therefore, a kind of PQ regulation is needed. Such regulation asks for reliable and transparent tools for monitoring and reporting the PQ levels.
Besides using these levels for regulatory issues, they can be used for coordination between the manufacturers of electrical equipment, the customers and the transmission and distribution companies.

Development
At the beginning of the development of the application, it has been recognized that the user interfaces and the related visualization techniques are equally important as the underlying data acquisition and processing algorithms. Therefore, from scratch much effort has been put to the development of the interface. This has been achieved by good communication between end-users, utility engineers and the developers of the application.
