102 Shipboard Electrical Power Systems
reducing the generator output voltage proportionally with speed below a
presettable threshold.
• The maximum excitation is limited to a safe value by internal shutdown of
the AVR output device. This condition remains latched until the generator
has stopped.
• Provision is made for the connection of a remote voltage trimmer, allowing
the user to nely control the generator output. The AVR has the facility to
allow parallel running with other similarly equipped generators.
• Typical transient response times are: AVR itself in 10 ms, eld current
to 90% in 80 ms, and machine voltage to 97% in 300 ms. The AVR also
includes a stability or damping circuit to provide good steady-state
