what is the difference between power transformer and voltage transformer?

The primary difference between a power transformer and a voltage transformer lies in their functions and applications. A power transformer is designed to transfer electrical energy between circuits at high voltages and currents, typically used in power distribution systems. In contrast, a voltage transformer, often referred to as a potential transformer, is used to step down voltage levels for measurement and protection purposes in electrical systems. Essentially, power transformers handle large power loads, while voltage transformers focus on voltage reduction for monitoring.
