Transformer Oil / Power Factor 1

[sky72]

Hi,

May i know what are the advantages using naphthenics base transformer oil compare to paraffinic base?

And, if the specification of transformer bushing power factor is < 0.7% at 20 degree C, what is the correction factor if i measure the bushing power factor at 34 degree C?

Thanks.
