An Losses transformers refer to the energy lost during the process of voltage transformation, which affects overall efficiency. These losses are typically categorized into core (iron) losses and copper (winding) losses. Core losses occur due to hysteresis and eddy currents in the transformer core, while copper losses result from the resistance in the windings. Understanding and minimizing these losses is crucial for improving energy efficiency and reducing operational costs in electrical systems. Explore how modern transformers reduce losses for better performance.
