Abstract
The increasing prevalence of non-linear loads in modern power systems introduces significant harmonic distortion, which directly affects transformer efficiency and operational losses. This research investigates the impact of harmonic currents on losses in three-phase transformer banks using a simulation-based framework. By modeling different harmonic scenarios and analyzing their effects on both load and no-load losses, the study quantifies performance degradation and identifies critical harmonic orders that contribute most to energy inefficiency. Findings indicate that specific low- and high-order harmonics disproportionately increase copper and core losses, emphasizing the need for targeted mitigation strategies in power system design. The methodology employs advanced simulation models validated against real-world parameters, providing actionable insights for both engineers and policymakers.
