← TechnologyWhich outcome occurs when harmonics propagate in electrical power distribution systems?
A)Transformer overheating and reduced lifespan✓
B)Improved power factor and reduced losses
C)Balanced three-phase load distribution
D)Decreased neutral current in the grounding
💡 Explanation
When harmonics propagate, excessive current flow and core saturation in transformers results because of nonlinear loads which produce harmonic frequencies. Therefore transformer overheating and decreased lifespan result, rather than improved power factor, balanced load, or decreased neutral current, each requiring dedicated power conditioning equipment.
