In parallel operation, which transformer carries less load?

In parallel operation, transformers share the load based on their impedance ratings. The transformer with higher impedance will carry less load compared to the one with lower impedance. This is because the impedance of a transformer affects the voltage drop across it when current flows.

When transformers are connected in parallel, the one with lower impedance has a greater ability to produce current. Therefore, it will take on a larger portion of the load, while the transformer with higher impedance will contribute less. This is an important concept in electrical engineering, as understanding load sharing is crucial for ensuring that transformers operate efficiently and safely within their rated capacity.

This principle is essential when designing systems that utilize multiple transformers, as an unequal load distribution can lead to overheating and reduced lifespan of the equipment. Therefore, in any practical application, attention must be paid to transformer impedance when planning for parallel operations.
