Well, the UK foul weather got to my RPC's transformer, the cover blew away in a gale and I just cleared 3 gallons or so of revolting once-rain-water from the bottom of its tank. That of course displaced the same amount of Diala-B transformer oil (fun clearing that up...), I have a fair few gallons of ISO VG32, 68 and 100 straight mineral oil and as Diala-B is "uninhibited mineral oil" according to Shell's www, is there any good reason NOT to use straight mineral oil to bring it up to the right level? (It only covers about half of the transformer windings). Transformer is low voltage (240 and 415) 9 KVA, when tested before reconnecting the earth resistance was above 5 MegOhms so it appears that sitting the trans in water was tripping the RCD...
