Brushless exciter system PRISMIC® A12

Introduction The PRISMIC® A12 is based upon proven technology and combines the experience and hardware of the complete range of BRUSH PRISMIC® products. It includes, additional features such as intergrated speed detection, power system stabiliser and synchronisation. The PRISMIC® A12 is produced on a plate mounted system either as a single channel or twin channel arrangement. As a twin system each controller acts as a hot standby for the other and is independently controlled with auto tracking, and smooth transfer. An optional colour display screen is also available. Key Features • Complete excitation system mounted on a plate • Available either as a single unit or as a high integrity twin configuration • Integrated Power System Stabiliser (optional) • Integrated auto synchroniser (optional) • Integrated speed detection eliminating need for seperate speed switch • Rotor earth fault detector input included eliminating the need for separate unit • Negative forcing of exciter field voltage • Modes of operation include generator terminal voltage control, power factor control, VAr control and offload VArs • Digital Outputs • Analogue Input Signal for special application • Auxiliary power supply input allows easy setting of unit without PMG supply present • Manual Reference • Soft start for controlled application of excitation • Diode Failure Detection and Indication • HMI (Human Machine Interface) software for advanced maintenance diagnostics and downloading of data • Oscilloscope style trending and analogue data logging (5ms resolution) via HMI • Event Logging
