Résumé:
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.
