The main reason for generation of harmonics in a transformer could be_______________?
Correct answer: D. saturation of core
- A. fluctuating load
- B. poor insulation
- C. mechanical vibrations
- D. saturation of core
Explanation
When the transformer core approaches saturation, the magnetizing current becomes non-sinusoidal and contains harmonic components. Fluctuating load, poor insulation, and mechanical vibration do not normally generate the principal transformer harmonics.
