Greg,

Putting heater elements under oil in a sealed container that also has
exposed wires carrying live 14.4kV might not be a great idea.  Think
vaporized mineral oil being ignited in a confined space.   This could be a
bomb in the making, and at the very least it could cause a very nasty oil
fire.  All this is aside from the fact that the oil is there as insulation,
and to keep the windings cool.   Just some considerations.

Zap!
