Which system degradation accelerates when transformer oil moisture exceeds limits?

💡 Explanation

Accelerated insulation paper degradation occurs because increased moisture accelerates hydrolysis via the esterification reaction creating more free acids; this constitutes a runaway *depolymerization* process. Therefore, cellulose breaks down faster than under dry conditions; rather than primarily thermal stress.
