IEEE (1992/2005) ST1A Model The computer model of the Type ST1A potential-source controlled-rectifier excitation system represents systems in which excitation power is supplied through a transformer from the generator terminals (or the unit's auxiliary bus) and is regulated by a controlled rectifier. The maximum exciter voltage available from such systems is directly related to the generator terminal voltage.
