Abstract
Electrical inductive apparatus having a tank, an insulating and cooling liquid in the tank, and an electrical winding structure immersed in the liquid. The insulating liquid includes an inorganic constituent in its formulation. The insulating liquid also includes a toxic organic contaminant which continuously leaches into the insulating liquid from the electrical winding structure. An adsorbent material is in fluid flow communication with the insulating liquid to remove the contaminant on a continuous basis by contact adsorption, to maintain the degree of contamination of the insulating liquid below a predetermined level.
