Development and implement of a prototype to measure the unbalance voltage level

The present work describes the stages accomplished in the development and implementation of a system based on microprocessor digital techniques, dedicated to inform the factor of unbalance voltage in a three-phase industrial power system, being constituted in a auxiliary technician support system for the improvement of the quality of the electric energy. In what concerns to the referred subject for now agreement, as well as in a support tool in the maintenance of industrial electric systems. To determine the necessary sequence voltages to execute the task of mensuration proposed, a very simple, and equally efficient, methodology is used, based on simple mensurations of the modules, which facilitated the accomplishment of the work.
