Why Transformer Oil Requires Regular Purification? A Complete Guide for Transformer Maintenance
Introduction Transformer oil is one of the most important components inside an oil-filled transformer. It provides electrical insulation between energized components and helps transfer heat away from transformer windings and cores. However, during long-term operation, transformer oil gradually deteriorates due to moisture contamination, oxidation, dissolved gases, and solid particles. These contaminants reduce dielectric strength, accelerate […]
