“…One of the studies reported that RBDPO Olein had almost the same characteristics as mineral oil [38]. The PD test was carried out based on needle-plane electrodes configuration with a 20 mm gap distance and an acrylic with a thickness of 15 mm was placed in between electrodes to prevent breakdown [35].…”

“…One of them is the PD pulses of RBDPO Olein spread in a much wider area than mineral oil. Secondly, the phase shift of PD occurrence for RBDPO Olein is bigger than mineral oil [38]. It was suggested that the phenomenon is due to the viscosity where the space charges in RBDPO Olein diffused into electrodes much slower than in mineral oil [38].…”

-Mineral oil has been widely used as dielectric insulating fluid in transformers due to its excellent performance in-service. However, there are few issues with mineral oil such as it has poor biodegradability and could contaminate the environment if a spillage occurs. With the increasing tight regulation on safety and environment, alternative fluids for mineral oil are currently being investigated and among the suitable candidate is the vegetable oil. There are different types of vegetable oils and one of them is the palm based oil. At the moment, extensive research works are carried out to examine its feasibility to be applied in transformers. This paper will review the previous research works that were carried out to examine the suitability of palm based oil as dielectric insulating fluid in transformers. The physical and chemical properties of palm based oil are studied based on viscosity, acidity, oxidation stability and flash point. Next, the electrical characteristics of palm based oil are examined based on AC breakdown voltage, relative permittivity, dissipation factor and partial discharge.

“…Minyak mineral adalah minyak isolasi yang bahan dasarnya berasal dari minyak bumi yang diproses dengan cara destilasi sehingga mempunyai sifat sebagai isolator dan juga sebagai pendingin [7]. Minyak mineral sulit terurai secara alami oleh migroorganisme dan rentan terhadap bahaya kebakaran [8]. Minyak isolasi mineral banyak digunakan pada transformator daya, kabel, pemutus daya (CB) dan kapasitor [9].…”

Kekuatan dielektrik minyak transformator nynas nitro murni dapat ditingkatkan dengan menambahkan berbagai partikel nano seperti nanoalumina (Al2O3). Penelitian ini bertujuan untuk melihat effek penambahan partikel nano alumina terhadap karakteristik tegangan tembus dan tegangan insepsi peluahan sebagian. Empat jenis minyak nynas dengan komposisi penambahan partikel nanoalumina sebesar 0.00%, 0.010%, 0.015% dan 0.020% diuji tegangan tembus dielektrik, tegangan insepsi peluahan sebagian (PDIV) pada suhu ruang dengan merujuk kepada standar pengujian IEC 60156. Hasil menunjukkan bahwa tegangan tembus minyak nanonynas meningkat sebesar 6% dan nilai tegangan insepsi dan peluahan sebagian lebih tinggi dibandingkan dengan minyak murni.

“…The high electric field necessary to produce a partial discharge is attained by utilising a needle plane electrode configuration. Since the electric field under needle plane configuration is non uniform, it produces maximum electric field [8]. To implement vegetable oils in high voltage apparatus, it is necessary to identify the PD characteristics using a needle plane configuration in vegetable oils.…”

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.
