1) Observe the oil level of the transformer: The oil in the oil-immersed transformer plays the role of cooling and insulation, and the oil level is although the temperature changes, so the transformer is engraved with the corresponding oil level at different temperatures, when the oil level is found to be too low, the temperature of the transformer should be measured and compared, and the transformer body should be carefully observed whether there is oil leakage, if the closed transformer should lift the air relief valve to check whether it is false oil level.

2) Observe the oil color of the transformer: the color of the transformer oil should be light yellow, transparent without debris, if there is black carbide found in the oil should be checked tap changer, coil, pile head lead line, etc., black carbide is generally caused by arc combustion.
3) Observe the porcelain bushing of the transformer: If the porcelain bushing plays an insulating role, the bushing surface should be clean, no cracks, no damage, and no discharge phenomenon.
4) Smell the transformer for odors.
5) Listen to the transformer has no different sound: the transformer should make a buzzing sound when it is normal, if there is a crackling sound, it indicates that the transformer has a short circuit.
6) Feel the temperature of the transformer: Feel the temperature of the transformer, compared with the past, if there is an increase, you should check whether the current of the transformer increases, whether the ambient temperature increases, whether the ventilation is smooth, and whether the sound is normal. The upper layer oil temperature of the transformer should not exceed 85 ° C.
