Transformer oil is an important medium that plays an insulating and cooling role in transformers, so it is very necessary to test it regularly. Under normal circumstances, transformer oil needs to be tested once a year to ensure the normal operation and reliability of the transformer.
Transformer oil testing mainly includes the following aspects: first, appearance inspection, to see the color, transparency and presence of suspended matter of the oil; second, physical property testing, including indicators such as flash point, dielectric strength, and water content; third, chemical analysis, to detect parameters such as gas content and gas composition in the oil; and finally, particle analysis, to evaluate the status of the transformer by detecting the number and size of particles.

By regularly testing transformer oil, faults and problems inside the transformer can be discovered in time, potential faults can be prevented, and the safe operation of the transformer can be ensured and its service life can be extended. Therefore, it is recommended that all units should pay attention to the detection of transformer oil when performing transformer maintenance, conduct inspections on time, ensure the normal operation of the transformer, and ensure the stable power supply of the power system.
