40KVA Epoxy Three Phase Auto Transformer 240/220/200/120/115/110/100V
Feature:
Winding two or more coils on a closed iron core, when one coil is connected to AC power supply (that is, the primary coil), alternating current flows through the coil, and this alternating current generates an alternating magnetic field in the iron core , The alternating main magnetic flux generates its own induced electromotive force in the primary coil, and at the same time the other coil (that is, the secondary coil) induces a mutual induction electromotive force. By changing the relationship between the primary and secondary coil turns ratio to change the primary and secondary coil terminal voltage to achieve voltage conversion, the general turns ratio is 1.5:1~2:1. Because the primary and secondary coils are directly connected, there is a risk of inter-level leakage. Therefore, it cannot be used as a light transformer.
