ST8C
Package: PowerDynamicsOpenAPIModels · Source: Dynamics/DynamicGeneratorComponent/AVR/ST8C.json
In these excitation systems, voltage (and also current in compounded systems) is transformed to an appropriate level. Rectifiers, either controlled or non-controlled, provide the necessary direct current for the generator field. Parameters of IEEE Std 421.5 Type ST8C Excitacion System. ST8C in PSSE and PSLF
