Which consequence results when inadequate core cooling occurs in a high-power electrical transformer?

💡 Explanation

Excessive heat from core losses initiates thermal breakdown via cellulose pyrolysis—a *decomposition reaction*: breakdown products catalyze the breakdown of insulating paper surrounding its winding. This occurs because higher temps speed up the reaction, therefore paper degrades rather than remaining insulative.
