This device consists of variable power, three-phase transformers, the measuring current meter, voltmeter, wattmeter, and three-phase load resistance to allow systematic practice of transformer. Especially it is made of components used in the actual field. To enhance effects of experimental practice, it uses a translucent front panel to visualize inside of the device. Also, the back panel opens architecture
