1. Project OverviewThis on-site purification process targets oil-immersed transformers during operation or maintenance, as prolonged operation often leads to issues such as insulation oil moisture absorption, contamination, aging acidification, and reduced breakdown voltage. To remove moisture, gase
Test preparationDisconnect all connecting wires, loads, and grounding wires on both the high and low voltage sides of the transformer in advance to completely power off and fully discharge the equipment. Clean the dust and oil stains on the surface of the bushing, keep the testing environment dry an
1. Core detection functionUsed for qualitative/quantitative detection of corrosive sulfur, free sulfur, and active sulfide content in mineral insulating oils such as transformer oil and instrument transformer oil. According to standards such as SH/T 0304, ASTM D1275, and IEC 62535, by simulating equ
