Frequently Asked Questions

• What is the primary function of this board? It provides de-excitation protection by safely dispersing field energy during generator shutdown using SCR technology.
• How does the backup protection work? If the SCR doesn't fire normally, overvoltage protection triggers when voltage exceeds the breakover diode threshold.
• What systems require this de-excitation board? EX2100 excitation systems and turbine generators needing controlled field energy dissipation during shutdown.
• What power does this board require? It operates on 24 VDC power supplied from the excitation control system.
• Where is this board typically installed? The board mounts in the auxiliary cabinet of the excitation control system for protection functions.
