What steps are covered in a transformer oil filtration procedure presentation?

A typical filtration procedure presentation covers preparation and safety, verification of oil type and condition, setup of a filtration unit, and selection of filtration mode such as heating, vacuum dehydration, and particle filtration. It then describes flow paths, hose cleanliness, sampling points, target limits for moisture and BDV, and criteria for stopping. It also includes post treatment sampling, documentation, and restoration steps such as re sealing, level checks, and monitoring for foaming or air bubbles. Some presentations include regeneration using adsorbents for acidity and sludge removal.
