The primary function is to transfer electrical energy between circuits via electromagnetic induction, changing voltage levels while maintaining frequency. It steps up voltage for transmission and steps down for safe use.
Typical primary voltages are 6–35 kV, and secondary voltages are 0.4–11 kV, as per IEC 60076-1. Actual values depend on the specific application and must be confirmed with the manufacturer.
The ratio is determined by the turns ratio of the primary and secondary windings (Vp/Vs = Np/Ns). By adjusting the number of turns, the transformer steps voltage up or down accordingly.
Key standards include IEC 60076-1 (general), IEC 60076-5 (impedance), IEC 60076-2 (temperature rise and cooling), IEC 60085 (insulation class), and IEC 60529 (IP rating). Compliance must be verified with the manufacturer.
