What does ALTC mean or stand for ?
A load changing tap is type of switch regulator that is used in transformers to increase or decrease the output voltage of that transformer.It achieves this by altering the turns ratio of the transformer and therefore adjusting the output voltage that is being delivered to the load.Most tap changers need to be manually regulated however there are some that are automatic and according to the load sanctioned it changes the windings to meet the demand.
