Purification is necessary to remove moisture, acids, sludge, and dissolved gases that degrade dielectric strength and accelerate insulation aging. Regular purification restores oil properties, improves cooling efficiency, and significantly extends transformer service life, reducing the likelihood of unplanned outages or failures.
