Unbalanced Type With Inner View of A.V.C with main TRF

The inner view of an Unbalanced Type Automatic Voltage Controller (AVC) with main transformer typically includes a voltage sensor, control circuit, variable transformer or tap changer, and the main transformer. The voltage sensor detects voltage imbalances, which triggers the control circuit to adjust the variable transformer or tap changer, which in turn regulates the voltage through the main transformer.
