Transformer Insulation | The Electricity Forum
Transformer Insulation Insulation systems in power transformers consist of a fluid—either liquid or gas—together with solid materials. Petroleum-based oils have been used to insulate power transformers since 1886 and the mid-1970s when the flammability of mineral oil was a concern, but it has since been completely phased out of transformer …Get Price Leave a Comment Read More
