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.application/pdfT Technology (General), TK Electrical engineering.
