Abstract

This paper reports on a comparative study ofstatistical Breakdown Voltage (BDV) in Persea americana oil(PAO) and mineral insulation oil (MIO) and their respectivemixtures. Two types of PAO are tested, that is extra virgin Perseaamericana oil (EVPAO) and refined Persea americana oil(RPAO). PAO and MIO and the oil mixtures (namely50%RPAO+50%MIO and 50%EVPAO+50%MIO) are subjectedto AC voltages. At least ten tests were carried out for each as perIEEE guide for the statistical analysis of electrical insulationbreakdown data (IEEE 930 or IEC 62539). It is shown that theaverage AC breakdown voltage of RPAO is higher than that ofMIO. It also observed that AC mean breakdown voltage of RPAOis higher than that of oils mixture (50%RPAO+50%MIO) andMIO. (50%RPAO+50%MIO) BDV is higher than that of MIO. ACmean breakdown voltage of EVPAO and MIO mixture is thelowest one. Thus PAO constitutes a potential liquid for replacingmineral oil in high voltage equipment.
