Design of On-line Monitoring System for Transformer Oil Chromatogram and Its Data Analysis

摘要

On-line monitoring system of transformer oil chromatogram works in laboratory. Using the basic principles of gas chromatography (GC) of the broad spectrum, the system provides online-testing of dissolving gases from oil with a single gas chromatographic column and sensors with high sensitivity. The single-chip is used to collect the data and control transformers. The main controlling computer realizes the function of analyzing and managing the collected data, by which transformer fault can be judged.
