Partial discharge (PD) properties and dissolved gas analysis (DGA) are investigated on two kinds of fatty acid alkyl esters synthesized from palm oil with additive, namely Pastell 2H-08 and Palm Fatty Acid Ester (PFAE) to be adopted in power transformers. For comparison, the properties of mineral oil which is commercially used transformer oil were also investigated in the research works. The results revealed that PD repetition rate number of the ester oils with additive increase remarkably at above 15 kV rms of voltage application than that of mineral oil. PD charge of ester oils with additive tends to saturate at about 10,000 pC, while PD charge of mineral oil seems to keep increasing with increasing the applied voltage at above 20 kV rms . The amounts of generated hydrocarbon gases in ester oils with the additive are higher than that of mineral oil. It is found that combustible gas pattern of the ester oils with the additive are different from that of conventional mineral oil. Duval analysis of ester oils with additive and mineral oil are classified as high energy electrical discharge, while for mineral oil is classified as low energy electrical discharge.

“…Recent reports have appeared on the development and practical use of environmentally friendly insulating oil for aiming at the construction of circular type society [1][2][3][4]. Among them, ester family insulating oils (ester oil) have good biodegradability and safety owing to high burning point compared with mineral oil [5][6][7].…”

Petroleum based mineral oils are mostly used for power apparatus insulation applications. They are not biodegradable and difficult to decompose the result of which has led to the development of vegetable based oils. Analysis of partial discharge characteristics of vegetable oil is very important, before suggesting it as an alternate to mineral oil for liquid insulation in high voltage apparatus. This paper deals with the analysis of partial discharge characteristics of extra virgin olive oil, castor oil and mineral oil. Partial discharge signals were measured with the help of an innovative PD detection system PDBASEII. The PRPD pattern, time domain and frequency domain characteristics of PD pulses of vegetable oils were measured and they were compared with the mineral oil. Preliminary results show that vegetable oils could be used as an alternate for mineral oils for high voltage insulation applications.

“…Moreover, in the last five years, numerous researches pertaining to the uses of natural ester as an insulating liquid in electrical power transformer had been extensively conducted either singly or in combination with mineral oil [8][9][10][11][12][13][14][15][16][17]. The selection is due to its compatible dielectric properties which best suit its function as an insulating liquid, fire safety advantageous and most importantly it is renewable and environmentally friendly product.…”

-This paper reported the experimental result of dielectric properties of Refined, Bleached and Deodorized Palm Oil (RBDPO) combined with 0-50% of Refined, Bleached and Deodorized Soybean Oil (RBDSO). The dielectric strength and relative permittivity of RBDPO/RBDSO was higher compared to mineral oil at all ranges of ratios and temperatures which indicated a positive sign for its possible use as insulating liquid in a transformer. All ratios of the RBDPO/RBDSO mixture also demonstrated lower dissipation factor compared to mineral oil at 40˚C, 70˚C and 90˚C. Apart from that, the kinematic viscosity for the oil mixtures shown exceeded the IEC 60296 as well as the mineral oil results. 70%RBDPO/30%RBDSO mixture ratio was chosen as the best mixing percentage after comparison was made with the mineral oil and IEC 60296 standard where the mixture accumulated the most satisfactory of dielectric properties hence making it as the potential candidate for palm and soybean-based transformer oil.
