Abstract
Description
The effect of the anti-o-;(idant (hydroquinone) on the breakdown" voltage of JJalm olein samples was
studied. The oil san1fles had different acid values resultir}g from the different degrees of
neutralization treatment~ ,given. The hydroquinone addition ranged from 0.23. to 1.13 weight percent
of the oil. ,
The hydroquinone. had a positive effect on the breakdown voltage of the oil samples. The
increase in the breakdown voltage was rapid at low concentrations of the :hydroquinone with the
tncr~ase tending towards an asymptotic value at higher concentrations. The effect of the
h"ydroquinone on the breakdown voltage was also dependent on the acid value of the oil. Oil samples
with lower acid values had sharper increases in their breakd.own voltages .. Percentage increase in the
breakown voltage of 6p.67(vis-a-vis the additive~less samples). was rec~rded for oil sample of acid
• value of 1 .515 mg KOH/tj oil and containing 0.45% by weight hydroquir;10ne. These. results show that
the one major problem !o. xidative stability) in the use ·of vegetable oil. as :transformer oil can be ~
overcome without an ad~e,rse effect on their electrical properties.
