480v to 400v 3 phase transformer

Understanding the 480v to 400v 3 Phase Transformer

A 480v to 400v 3 phase transformer is an essential electrical device used to convert voltage levels for three-phase systems. This transformer enables industrial equipment designed for 400 volts to operate effectively in environments where the supply voltage is 480 volts.

How Does a 480v to 400v 3 Phase Transformer Work?

The transformer functions on the principle of electromagnetic induction. It steps down the voltage from 480V to 400V while maintaining the power frequency. The relationship can be represented by the formula:

V1/V2 = N1/N2

where V1 is the primary voltage (480V) and V2 is the secondary voltage (400V). The turns ratio of the transformer coils determines the voltage reduction.
