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
As the core equipment of the power system, the operational reliability of transformers directly impacts the safety and stability of the power grid. During routine maintenance, handover acceptance, and preventive testing, various professional testing instruments are utilized to conduct comprehensive
1. DC Resistance TestMeasure the DC resistance of each phase winding using a three-phase DC resistance tester and compare the three-phase imbalance. If the resistance deviation is excessive, the values fluctuate abruptly, or the three-phase difference exceeds the standard, it can be determined that
