Today's liquid-filled transformers have their windings immersed in highly refined mineral oil (combustible), silicone fluid, edible seed oil-based dielectric coolant, or other acceptable nontoxic liquids that have ____ properties.

Question

Quizplus · Accepted Answer

The correct choice is A) high dielectric because the liquids used in transformers need to have high dielectric properties to insulate and prevent electrical discharges, not conduct electricity (which would be indicated by high conductance), nor do they need to be photoactive or have low dielectric properties for their function.
