Transformers are the backbone of any power system, and they require continuous monitoring and protection. The usual problems occurring in the transformers are bushes failure, cooling system failure, Main tap failure, and Tap changer failure. Backed by 35 years of innovation, EPESOL can provide one device, online and offline solution to these problems. EPESOL provides an advance and efficient product line for single and multi-dissolve gas analysis (DGA). Transformer oil gas analysis can indicate many issues, but DGA alone can't detect all the problems, so along with single, multi, and portable dissolved gas analysis, EPESOL also provides Bushing and complete monitoring devices. EPESOL's offered advanced solutions such as Transport-X can give on-site Dissolve Gas Analysis results within 30 minutes of testing.
