As the only moving component inside transformer tank, on-load tap changer needs to be highly reliable both electrically & mechanically. By different means, tap changers can be divided into different categories. By operation mode, it can be on-load or de-energized (off-circuit) tap changer; by arcing extinguishing medium, it can be conventional (arcing in oil) or vacuum (arcing in vacuum interrupter) tap changer; by structure, it can be selector switch or diverter switch tap changer; by mounting method, it can be in-tank or on-tank (bolt-on) tap changer; by transition impedance, it can be resistive or reactive tap changer; and by insulation medium, it can be liquid immersed, air insulated or gas insulated tap changer.
