Which outcome occurs when harmonics from non-linear load interact with transformer impedance?

💡 Explanation

When harmonics from non-linear loads flow through transformer's impedance, harmonic voltages will be generated, leading to increased voltages, especially around saturation knee. These elevated voltages cause higher peak fluxes, thus provoking core saturation. Therefore, core saturation increases, not improved regulation, efficiency, or noise reduction, which depend on harmonic filtering.
