Tips: ATO three phase isolation transformer working principle

Three phase isolation Transformer mainly applies electromagnetic induction principle to work, the working principle details are as follows: When the primary side of the isolation transformer is applied with the alternating voltage U1 and the current flowing through the primary winding is I1, then the current will generate alternating magnetic flux in the iron core to generate electromagnetic connections between the primary winding and the secondary winding.

According to the electromagnetic induction principle, electromotive force will be induced when the alternating magnetic flux goes through these two windings. The magnitude of electromotive force is proportional to the winding turns and the maximum main flux, the voltage of more winding turns is high and the voltage of less winding turns is low. When the secondary side of the transformer opens circuit, that is to say when the transformer is no-load, the primary and secondary end voltage is proportional to the number of the primary and secondary winding turns, that is U1/U2 = N1/N2, but the primary and secondary frequency stays the same to realize the change of voltage.
