Transformer Oil Gas Analysis

Analysis of the dissolved gases in transformer insulation and cooling oil is critical to ensuring the safety and longevity of the electronics in which they are used. Over time, thermal and electrical stresses cause the formation of various gases dissolved within the oil. Shimadzu offers a System GC compliant with ASTM D 3612 Method B with direct oil injection and ASTM D 3612 Method C with headspace sampling.
