2).Distributing loads between networks using on-load tap-changing acting as interconnection transformer between two networks.

1).Stabilizing electric-network volage in every on-load center to icrease quality of power supply.

On-load Tap-changing Transformer is mainly used for:

On-load Tap-changing Transformer is a transformer whose several tap joints are educted from transformer winding passing through on-load tap-changing switch and change tapping location and its effective number of windings in case of ensuring not to rupturing load current and thus making use of changing transformer ratio to aim at unchangeable output voltage. Energy during changing and tapping process usually utilizes transition resistance to absorb limtation cycle current.

The transformer equipped with on-load tap-changing switch is called as On-load tap-changing Transformer.
