DGA Standard
Gases, formed by normal and abnormal events within the transformer, are dissolved in the oil. By analyzing the volume, types, proportions, and rate of production of dissolved gases, much diagnostic information can be gathered. Since these gases can reveal the faults of a transformer.
Few examples of Natural Gas Standard are given below
| CH4 100-1000ppm + C2H6 100-1000ppm + C2H4 100-1000ppm + C2H2 5000ppm + CO 5000ppm + CO2 50-5000ppm+ N2 4000-20% + Argon Balance | CGM08360410 |
