Changes of Oil-immersed transformers

Which generation does your equipment belong to?

Recommendation of Upgrade


We diagnosis the remaining life time and also propose the best Upgrade plan for your transformer.

Do you have transformers that have been in use for more than 25 years? The life expectancy of a transformer is 30 years.
“Damage of accidents caused by deterioration is huge.”
“Please note that there are risks of failure even though if your transfer is still in use. ”
”We estimate a remaining life of a transformer with high accuracy using our original structured neural network.”

The level of aged deterioration and condition of insulating oil can be judged from the analysis of internal anomalies.

Benefits of Upgrade

Upgrade of aged transformers will bring you not only improved reliability of the transformers but also higher performance due to the up-to-date manufacturing technologies used. Also by replacing H-class dry-type transformers and oil-immersed transformers with molded transformers, you can enjoy huge benefits such as significant operational cost reduction and overall performance improvements including low loss, small size and lightness, fire resistance, insulation performance, humidity resistance and maintainability.
