WHY PURIFIERS ARE NEEDED FOR TRANSFORMERS from luis huang's blog

Transformer oil filtration machines use oils for a variety of purposes including cooling and insulating. They are essential parts of any electric unit which uses electricity to power various sources. The oil is used for cooling the various parts of the transformer so that any chance of over heating or short circuiting is eliminated. The oil also helps to insulate various parts of the device where any kind of outside temperatures are negated by the oil. However, the oil inside the transformer tends to break down over time. Fine particles may accumulate inside the oils which can severely affect the life and the functioning of the transformer. This where an oil purifier is used. A mobile transformer oil purifier will help to filter out moisture and sludge from inside the vent systems. It helps to clean the oil from any extra ingredients and keeps it viscous and flowing through the insulating vents.
