Brushless exciter system PRISMIC® A32

The BRUSH PRISMIC® A32 excitation controller or automatic voltage regulator (AVR) incorporates all the features usually required for control of a Brushless generator equipped with a single phase permanent magnet generator (PMG) pilot exciter. Introduction The A32 includes two fully featured independent controllers and two independent power circuits within a single 6U 19 inch enclosure. Each controller acts as a hot standby for the other and each channel is independently controlled with automatic tracking included to enable smooth transfer from one controller to the other Key Features • High integrity dual redundant excitation system in a single 19 inch enclosure • Built in power system stabiliser • Negative forcing of exciter field voltage • SCADA/DCS communications using Ethernet EGD or RS232/RS485 Modbus protocol • Conforms to CE directives and CSA/UL approved • Compatible connections with earlier BRUSH products for easy upgrades • Automatic tracking between channels in all modes • Built in colour TFT operator interface • Including PC Human Machine Interface (HMI) software for advanced maintenance diagnostics and downloading of data • Digital (discrete) outputs for remote status indication • Analogue input signal for special applications • Modes of operation include generator terminal voltage control, power factor control, var control and offload vars • Monitoring of rotating rectifier health and diode failure indication
