Does any one know of any articles on the proceedure for taking Transformer oil samples and maybe a list of do and do nots?

Also does anyone know the best way to get rid of old transformer oil?

Maybe DOE or Noria websites contain this informstion.

Also you might ask for instructions from your lab especially if they provide you with syringes. That would also include handling of the sample syringes after they're drawn.

A few thoughts:

Never try to sample an energized instrument transformer. (CT or PT). It may cause a violent explosion. Stay away from sampling deenergized bushings unless you really know what you're doing with respect to cleanliness.

Check for indication of positive pressure before you open a sample valve.

There's no substitute for training.

Mike,

I tried to call you several times today to discuss the Transformer Oil testing. Please email me when it may be a good time to call you.

PredictUSA may also be a source. Check 'em out and ask for Doug Holmes.

1)Read ASTM D3613-98 and ASTM D 923-97
2)Neta has two or three interesting articles on this matter. See electricpete's post above.
