Detailed Product Description
Oil Acidity Test kit to measure the Acidity of oil used in Transformers.
Acidity Test
New transformer oils contain practically no acids if properly refined. The acidity test measures the content of acids
formed oxidation. The oxidation products polymerize to form sludge which then precipitates out. Acids react with metals
on the surfaces inside the tank and form metallic soaps, another form of sludge. Sludging has been found to begin when
the acid number reaches or exceeds 0.4, and 0.4 is considered to be the normal service limit. New oil has as acid
number of less than 0.05. the acid number (formerly referred to as neutralization number) equals the milligrams of KOH
(potassium hydroxide) required to neutralize the acid contained in 1 gram of oil. It is questionable whether an oil that is
deteriorated to the point where its acid number exceeds 0.6 can be put back into lasting good condition by a single
renovation. It is almost certain that two or more renovations, spaced 6 months to 1 year apart, would be necessary. It is
recommended that an upper limit of 0.2 be used to determine when oil should be renovated, as a single renovation would
most probably restore such an oil to very good condition. Oil showing an acid number of 0.15 or larger can be expected
to show accelerated acid formation. Tests have been conducted which indicate the acidity is proportional to the amount
of oxygen absorbed by the oil. It is estimated that 0.0015 m3/L (0.2 ft3/gal) of oxygen absorbed in oil will cause an
acidity of about 0.4 mg of KOH, which is the approximate acidity number at which sludging is assumed to start.
