The growing demand for energy in electric systems has resulted in greater difficulties to operate them. This has led specialists to deal more strictly with the control of reactive power and voltage, mainly in the case of radial electric systems, for the supply of seasonal loads. For this purpose, static compensators represent an alternative of great potential to control the power flow and improve the voltage profile of electric systems. In this context, the SCRSC or Saturated Core Reactor Static Compensator - made up of a magnetic core with special characteristics and winding and a set of capacitors in series and in parallel - becomes an interesting alternative, when compared to other types of equipment being sold at present, due to its robustness, low cost, fewer maintenance requirements and good performance. Within this scenario, the purpose of the present dissertation is to research the performance of a saturated core reactor prototype connected to a supply network, in order to assess its effectiveness and the effect on its quality standards, as for example: voltage peaks and valleys, harmonic distortions, unbalance, temperature and noise. Thus, tests were carried out on a saturated core reactor prototype to evaluate the following issues: transients as a result of prototype energizing; correlation between voltage and reactive power; definition of the harmonic components of voltage and current; analysis of the thermal performance in continuous operation and noise level verification during operation.
