  • 12 on-site checks to inspect the transformers health

    8 mins readDec 21, 2019They should check the entire transformer for oil leaks. Leaks usually develop due to gaskets wearing out, ultraviolet exposure or from expansion and contraction, especially after transformers have cooled, due to thermal shrinkage of gaskets and flanges. Many leaks can be repaired by applying an epoxy or other patch.
