How to identify the oil quality of oil-immersed power transformers
Jan 09, 2021
1: Odor, when the transformer oil has no odor or has a little kerosene or other odor, it means that the oil has deteriorated, so at this time we need to replace it with new oil in time.
2: According to the color of the oil, because the new oil is generally light yellow, the color of the oil will become dark when it is used for a long time. If this happens, we need to replace the new oil.
3: Transparency When we look at the new oil, it is relatively transparent and also has purple fluorescence. If there are impurities and free carbon, it is not a new oil. We should pay attention to it when replacing it.
