Re: [TCML] xfmr oil



Hi marko,

I don't really know anything about refrigeration oil, but I do know that
mineral oil is suitable for high voltage uses.  There are oils specifically
designed for high voltage applications but mineral oil is a decent
substitute.  The only problem with oils and high voltages is that any water
or other impurities can make it much more conductive.  My uncle flies small
aircraft in developing countries and rural areas where sometimes the
gasoline is questionable.  He carries what looks like a pack of mentos (a
candy) with a "SHELL" logo on it.  He puts them in the gasoline in question
and if there is water in it they turn blue.  I don't know where you could
get any of them, but the point is if you want to use unknown oil for TC use
you should see if it has water in it first.

Regards,
Drake Schutt
