In a typical distribution step voltage regulator, are both windings connected electrically and magnetically?

In a typical distribution step voltage regulator, both windings are indeed connected both electrically and magnetically. This dual connection is essential for the voltage regulation process.

The regulator works on the principle of electromagnetic induction, where the primary winding is energized by the input voltage, creating a magnetic field that induces a voltage in the secondary winding. The two windings are wound around a common magnetic core, which allows for efficient transfer of energy through magnetic coupling. This design enables the regulator to adjust the output voltage to maintain a consistent level, compensating for fluctuations in the input voltage.

Thus, the connection of both windings in parallel allows the regulator to operate effectively, ensuring that changes in load or input voltage can be compensated for, providing a stable output.
