摘要：
Assessing the amount of remaining mineral oil in retrofilled transformers is vital since that presence may worsen flash and fire point of the ester and impact the transformer dielectric performance; this article proposes a new experimental methodology to quantify the ratio of mineral oil in natural esters.
