Abstract

The separation and detection modules of the chromatographic system for the transformer gas-in-oil on-line monitoring is improved. The former single-column separation detection module is improved to double-column separation detection module, and compared with single-column detection module. The results show that the double-column detection module has a better separation performance and the separation process could be completed within 13min. The new detector has a linear response for all the fault gases in the whole detection range, which greatly reducing the workload and calibration time. The system exhibited good stability and high accuracy. The deviation of repeated test is less than 5%, and the deviation from off-line measurement is less than 15%.
