Which risk increases when a distribution transformer is subjected to prolonged harmonic distortion from non-linear loads?

💡 Explanation

When subjected to harmonic distortion, increased eddy current and hysteresis losses occur because non-sinusoidal currents flow through core, raising the core and winding temperatures. Therefore elevated insulation temperatures result, rather than lamination issues, enhanced dielectric strength or reduced noise, all dependent on different electrical or mechanical factors.
