Gas Chromatography Analysis Used for Faults Diagnosis of Traction Transformers

Chromatographic analysis of the dissolved gases in insulation oil of the traction transformers are carried out regularly in shenzhen railway power supply section. According to all previous test records or repetitive sampling test results and reviewing gas-generating rates of the traction transformers, especially based on the characteristic gases method and IEC-3-ratio method combined with electrical tests, chromatography analysis is applied to estimate whether faults exist in the interior of traction transformers, how serious faults are and how faults would develop.
