hi iam AVR Service engineer .
AVr is heart og genset .its developing & maintain the
genset voltage as constant .its building voltage by
refernce of voltage produce by genset .for Ex: if genset
rated voltage is 11kv means intially genset produce some
minimum voltage (7- 14v)ac only is called resuidual
voltage .
that voltage is input of AVR .avr developing the
voltage upto rated Kv by some programmable circuit in
AVr .that O/p voltage is DC only its called as Excitation
voltage. we fed the excitation voltage to Excitor in
genset.after genset reached rated KV the AVr continusly
maintain the voltage as constant
