how does a control power transformer work?

A control power transformer works by stepping down the voltage from the primary power supply to a lower voltage suitable for control circuits. It typically has a primary winding connected to the high-voltage source and a secondary winding that provides the reduced voltage. The transformer operates on the principle of electromagnetic induction, where alternating current in the primary winding creates a magnetic field that induces a lower voltage in the secondary winding, ensuring safe and efficient operation of control devices.
