DGA chromatographic working station collects and processes the chromatographic signal of gas which sampled from transformer oil. It calculated the consistency of various kinds of dissolved gas in insulating oil. Its features are as follows:

1. Automatically report Three-ratio code, fault nature and typical example;

2. The management of chromatogram charts of oil samples can be achieved based on sampling points (create, add, delete, modify, query and sort);

3. The equipment analysis file card can be generated based on each analysis result of the same equipment; automatically calculate growth of total hydrocarbon, rate of gas generation etc.;

4. The trend curve which indicates the change of each gas composition content upon the variation of time can be built for the same sampling point;

5. Sample-analyzing results can be summarized in one report, and calculate their average value, standard deviation and relative standard deviation;

6. Chromatogram peak intelligent identification technology, minimizing the operator's work for setting required processing parameters of chromatogram chart, basically achieve peak-judging, baseline-correction and overlapping peaks-separating;

7. Function of manual precision-cutting off deflection peak from tailed peak, so that tiny compositions can be analyzed quantitatively;

8. The chromatogram charts (including analysis results) can be forwarded to superior departments or authorities for analyzing and checking via "Send" function;

9. Quantitative analysis results and notes etc. directly recorded in Access database.
