How To Achieve Electrical Isolation In A Constant Voltage Transformer?

3 phase constant voltage transformer establishes an isolation barrier between the power supply and the load by physically separating the input and output windings, creating a barrier with no direct conductive path. The input and output windings are not connected to each other; energy transfer between them relies entirely on electromagnetic induction. This means that alternating current is coupled via a magnetic field, without the need for direct current flow through conductors.

Inside the constant voltage transformer for home, workers typically arrange the primary and secondary windings separately and add the necessary insulation materials. This engineering layout also suppresses capacitive coupling between the windings, significantly reducing the possibility of high-frequency interference transmission. Because the alternating current signal is linked by magnetic flux, a potential change on either side does not directly affect the current in the opposite circuit, thus achieving true electrical isolation.
