Which consequence results when a transformer's molecular drying agent degrades?

💡 Explanation

Winding insulation breakdown is more likely during aging; the desiccant removes moisture, preventing hydrolysis. Hydrolysis increases conductivity via ionic mobility increases, therefore insulation performance degrades because moisture-induced conductive pathways form, rather than other disruptive effects due to heat or saturation.
