Regulador trifásico de tensão por fase.

Abstract

In this work we designed a three-phase voltage regulator, which acts individually on each phase automatically or manually supplying the load a voltage stabilized in all three phases. The control circuit voltage was designed as simple and objective as possible, so as to adjust the phase voltage automatically with an adjustment of 5% or 10%. The main objective of this study was to develop, with the company Transformadores Campinense, a device that controls the tension in a three-phase auto-transformer for testing of distribution transformers, transformers for these trials using single-phase or three phase small. The autotransformer designed to function as voltage regulator has a star configuration, with a power of 10 kVA.
