ABB REG650 User Manual

motor drawing a large current from the system. The voltage supervised overcurrent
protection is used to protect the inadvertently energized generator.
Accidental energizing protection for synchronous generator (AEGGAPC) takes the
maximum phase current input from the generator terminal side or generator neutral
side and maximum phase to phase voltage inputs from the terminal side. AEGGAPC
is enabled when the terminal voltage drops below the specified voltage level for the
preset time.
