Transformer, 6 kVA, 3-Phase, 480 Primary, 24 Secondary, Cu Winding

A transformer is an electrical device which converts alternating current from one voltage to another. It can be designed to increase or decrease voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static, solid state device, which insures under normal operating conditions, a long and trouble-free life. A transformer consists of two or more coils of insulated wire wound on a laminated steel core. When voltage is introduced into one coil (called the primary), it magnetizes the iron core. As a result, a voltage is induced into the secondary, or output coil. The change of voltage (voltage ratio) between the primary and secondary depends on the turns ratio of the two coils.
