Introduction:
Transformer oil tends to deteriorate with time and gradually begins to decay, In addition to these reasons, the presence of high temperatures, oxygen, and water, the catalysis of the materials present in the transformer; all combined to cause deterioration of the oil condition. Such processes also tend to release certain by-products that are highly acidic-finally resulting in high deterioration of the oils; and ultimately the transformers. ZYD Transformer Oil Filtration is required to improve the performance of the insulating oil. It can effectively remove acidity, moisture, traces of water, dissolved gases, and particulate matter in insulating oils, which ultimately improves the performance levels of transformers, circuit breakers, transformers, cables, and capacitors. All of these devices and machines have an insulation system.
