2.2 - PMG excitation system
With PMG excitation, a permanent magnet
generator (PMG) added to the alternator
supplies the AVR with voltage which is
independent of the main alternator winding.
This system provides the machine with a
short-circuit current capacity of 3 IN for 10 s.
The AVR monitors the alternator output
voltage by adjusting the excitation current.
The rotating switch should be in the PMG
position (see 3.2.3).
