Tips: Single phase vs. three phase isolation transformer

The single-phase isolation transformer is a device that uses the principle of electromagnetic induction to step-up or step-down the AC voltage, among which the primary coil, secondary coil and magnetic core are its main components. At the same time, it is worth mentioning that single-phase isolation transformer is different from three-phase isolation transformer in terms of input and output power types. In the former, both input and output are single-phase AC power supply and only single-phase power supply is needed for single-phase electric load. The three-phase isolation transformer input and output are three-phase symmetrical alternating current, and it can provide two different types of power supply of three-phase power and single-phase power. Besides, three independent windings are used in the three-phase isolation transformer, which can use different connection methods to input and output three-phase AC power supply.
