AVR-Automatic voltage regulators. alos they are called line
drop compensators. they are used to regulate the supply
voltage to the distribution network. thay r used in
transformers and generators. they sense the secondary PT
voltage and correspondingly change the tap position of OLTC
to regulate the secondary output voltage.
