GAVR-20A Automatic Voltage Regulator (AVR)

Description

What the GAVR-20A Does

The GAVR-20A is a half-wave, phase-restricted thyristor-based AVR that forms part of the excitation system in a generator. Its job is to:

• Regulate generator output voltage automatically.
• Protect against under-frequency and voltage spikes.
• Provide soft-start ramping to avoid sudden voltage surges.
