For asset managers and equipment engineers, mastering Dissolved Gas Analysis (DGA) interpretation is essential, because gases like carbon monoxide and carbon dioxide are the first chemical signals that a transformer's solid cellulose insulation is overheating and degrading. Your transformer can talk, and if you know how to listen, you will hear it. Inside every oil‑filled power transformer, a silent story unfolds as the oil and paper insulation bear the brunt of electrical stress, thermal cyclin
