Motor Síncrono Trifásico como Compensador Síncrono | Controle de Fator de Potência #26a

Did you know that one way to correct the power factor in large industries and substations is by using a Three-Phase Synchronous Compensator (or Capacitor)? It replaces capacitor banks and allows for fine-tuning of the reactive power delivered or consumed by the machine. A synchronous capacitor is simply a synchronous motor operating at no load, that's right, without any mechanical load on the shaft. Controlling the field current allows for controlling its power factor. However, due to its high cost, it is only worthwhile in large-scale systems. Machines with more than 20 MVA. In this practical exercise, we obtained in the laboratory the well-known V-curve of a three-phase synchronous motor operating at no load, the so-called Synchronous Capacitor. It's important to review some previous lessons: Principles of Synchronous Motors:    • Como funciona um MOTOR SÍNCRONO TRIFÁSCICO...   Starting a Synchronous Motor: Theory:    • Partida do Motor Síncrono Trifásico | Inve...   Practice:    • Partida direta e com Inversor de frequênci...   Have a good lesson everyone.
