What are the technical considerations for oil transformer maintenance?

Technical considerations for oil transformer maintenance include regular monitoring of insulation oil quality, including moisture content and acidity levels, to prevent degradation. Routine inspections should assess the physical condition of the transformer, including connections and seals. Additionally, implementing thermal imaging can identify hot spots, while dissolved gas analysis (DGA) helps detect potential faults. Regular cleaning of radiators and ensuring proper cooling system functionality are also critical for optimal performance and longevity.
