How To Adjust The Voltage Of American Transformers

Non excitation voltage regulation: This voltage regulation method utilizes the changes in magnetic flux inside the coil for voltage regulation. During the voltage regulation process, no AC power is introduced into the coil, so the coil does not generate induced voltage. Its voltage regulation principle is basically the same as that of electric furnaces or electric heaters, and belongs to one of the no-load voltage regulation methods.
On load voltage regulation: On load voltage regulation of American box transformers is achieved by setting on load tap changers to regulate voltage. This transformer has several wires connected to the input end of the transformer, and an on load tap changer is fixedly installed on the housing. The terminals of the on load tap changer are connected to the wires one by one. In this way, the output voltage adjustment range of the American box transformer body is greatly increased, reducing the voltage variation amplitude between levels, so that the output voltage can meet the usage requirements, while avoiding power waste
