ESAC6A

Package: PowerDynamicsOpenAPIModels · Source: Dynamics/DynamicGeneratorComponent/AVR/ESAC6A.json

This excitation systems consists of an alternator main exciter feeding its output via non-controlled rectifiers. The exciter does not employ self-excitation, and the voltage regulator power is taken from a source that is not affected by external transients. Parameters of IEEE Std 421.5 Type AC6A Excitacion System. ESAC6A in PSSE and PSLF
