Transformers are essential to the electrical power business. Transformers transform power to safe levels for usage by other system components. Transformer Oil Filtration must be done to ensure their longevity. In addition, clean, high-quality oil is required for the transformer to operate well.
Over time, transformer oil starts to deteriorate. The oil is exposed to unwanted substances such as acids, metal particles, and dampness, among others. When transformers contain dissolved gases, dust, and other impurities, it is important to filter and purify the transformer oil.
Oil is treated utilizing in-line transformer oil filtration Service as part of transformer maintenance. Here we will see why transformer oil filtration is needed.
To comprehend why transformer oil filtration service is essential, one must first comprehend the function of transformer oil. Transformer oil serves two major purposes:
·         To serve as a transformer insulating layer.
·         To function as the transformer’s coolant.
For these reasons, transformer oil must be chemically and electrically stable and temperature stable.

Regarding Transformer Oil Filtration

Transformers need oil that has been filtered and dried. During use, the insulating oil collects moisture and becomes contaminated with wet fibers, filthy particles, aging byproducts, and soot. Even unused oil is not sufficiently clean since it may have collected moisture from the air or become contaminated in its storage barrel.
The oil’s effectiveness as an insulating medium decreases drastically as its moisture content rises. Therefore, filtering transformer oil is a crucial operation that removes solid particles, dissolved gases, and dissolved water. Filtration, dehydration, and degassing can be used to improve the oil’s electrical characteristics. 

The Importance of Transformer Oil Filtration

Due to the growing rating requirements of contemporary transformers and electrical equipment, insulating materials and fluids are subjected to higher electrical stress. To withstand these increased stresses, oils must have a higher dielectric strength and have reduced residual water content. The timely and effective treatment of these insulating fluids will enhance the qualities of the power transformers’ whole insulating system.
The insulating fluid serves primarily as a dielectric substance and efficient coolant. To accomplish these roles, the insulating fluid must have precise properties at the time of initial setup, and these qualities must be maintained in the field if optimal performance is to be achieved.
Nearly seventy-five percent of transformer failures are caused by polluted and degraded oil. It is essential to filter transformer oil. Regular maintenance is crucial since replacing or repairing a transformer is an expensive endeavor. Ignoring transformer oil filtration might result in:
·         Arcing.
·         Overheating
·         Coronal Discharges
·         Decrease in the transformer oil’s insulating properties, and more.
