Nanofluids were fabricated by employing nanoparticles with different dielectric properties as modifiers to improve the dielectric performance of the mineral oil. Breakdown voltages under AC and lighting impulse stresses were measured to evaluate breakdown strength of these nanofluids. The results indicated that the addition of semiconductive nanoparticles to the base oil can improve the breakdown strength at the optimum concentration of nanoparticle. However, the insulating nanoparticles were unfavorable for the overall dielectric strength of the nanofluids. A possible mechanism was discussed based on the physical properties of the suspended nanoparticles.

The number of aged power equipment increases and it is important to clarify the characteristics of deteriorated insulating oil. This paper describes the basic study on transmittance spectra of oxidized insulating oils by terahertz spectroscopy. First, the mineral and mixture insulating oils heated in oxygen were measured and observed spectra change. Second, the oxidation process of insulating oil was modeled by using various compositions of dodecane and 2-octanol. The absorption related to hydroxyl groups (-OH) was significantly observed between 6 and 7 THz. And hydrogen bonds were observed from vibration change of OH. The absorption band was also observed in accelerated aging insulating oils used in power equipments as insulating oil.

The electrical insulation system of power transformers is a combination of mineral oil and pressboard materials. We have measured the influence of forced oil flow on the electric field stress in oil pressboard insulation system with applied DC potential using Kerr electro-optic effect. The data show a variation in the electric field strength in flow direction, depending on velocity, time and applied voltage. The observations are explained by variation in space charge distribution on the pressboard.

This paper reports on a comparative study between mineral and ester oils basing on DGA (Dissolved Gas Analysis). Electrical (breakdown of low energy) and thermal (stray gassing) faults are realized at laboratory scale and gas formation as well as diagnosis methods are compared. Two extraction methods described in IEC 60567 were used: total vacuum degassing and stripping method. Three different diagnosis methods were used: IEC 60599 gas ratios, Duval's triangle and key gases. It appears that for electrical faults and especially for low energy discharges, the same gases (Hydrogen and Acetylene), in relatively same ratios, are created. It is shown that classic Duval's triangle is well applicable for this type of fault confirming thus the results reported in literature. For thermal faults and especially for stray gassing issue (low thermal faults), Ethane (associated with Hydrogen) constitutes the key gas of natural esters and the new Duval's triangle can be applied for mineral oil whereas some arrangements need to be introduced for ester oils.

Investigation of the difference in the ageing process for several thermally upgraded and non-upgraded papers in transformer oil was performed. We observed that the level of nitrogen in the papers is crucial for the resistance towards hydrolysis. One of the papers in the experiment did not fulfil the upgrade specification with respect to the nitrogen level (data sheet). For hydrolysis of wet oil impregnated samples in argon atmosphere the upgraded papers seem to degrade less than non-upgraded papers. The paper with highest level of nitrogen degrades less than those with lower levels. The Insuldur process seems to be the best way of thermally upgrading the paper (Upgrade 1) and this also gives the highest level of nitrogen. For one of the upgraded samples (Upgrade 2) the nitrogen disappears completely after startup and this paper behaves as non-upgraded for the highest temperature. Dry oil impregnated paper (0.2% water content) under argon atmosphere does not seem to be hydrolysed and ages at a very slow rate. In the case of oxidation of dry oil impregnated samples (0.2% water content) in air there are initially no significant difference between non-upgraded and upgraded papers. However, the upgraded papers seem to have an improved performance after the water production from ageing becomes significant. The oxidation activation energy for non-upgraded paper is lower compared to hydrolysis and for upgraded paper this difference is smaller.

The deposition of copper sulphide within oil filled high voltage equipment is the symptom of the use of sulphurous oil. In some cases, severe copper sulphide contamination has resulted in expensive equipment failure. It has been shown that sealed equipment, containing sulphurous oils and operating at elevated temperatures, are the more susceptible to the copper sulphide deposits. Recent work has suggested a mechanism for the deposits in the paper covering the copper conductors. Other work has suggested that the deposition may be the result of thermally driven gassing. However, the overall mechanism of copper sulphide formation and its deposition on the copper is still a topic of interest.

It is known that the oxidation decay of oil in power transformer deteriorates the paper insulation of windings. To avoid the formation of incipient electrical failures, service providers recommend timely reclamation of liquid insulation. Even though the purity of oil is improved, the decay products previously adsorbed by the paper cannot be removed. Another setback is the unknown gassing tendency of reclaimed oil. This contribution shows that not only the reclamation improves the gassing tendency of oil, but also the type of Fuller's Earth affects this important property. By upgrading the analytical chemistry of oil the predictive maintenance of this non-renewable resource is modernized, its cost diminished and the service reliability of transformers enhanced.

The free volume model has in the past been used to calculate ionic conductivities of liquids and solids successfully. We have recently applied this method to calculate electron mobilities and electron cavity radii in liquid and supercritical helium. A key step in our approach is the development of van der Waals-type state equation with an appropriately chosen expression for the internal pressure describing the attraction between fluid and impurities. Here we develop this approach further to study positive ions. We find for positive ions a much simpler form of the internal pressure than for electrons. The ion mobility calculated with our method for pressures between 1 and 100 bar agree very well with experimental data recorded at 2.2, 3 and 4.2 K. The radii associated with mobility values vary from 0.55 nm to 0.4 nm with pressure or density. In liquid helium, positive ions form ‘Atkins’ snowballs, a structure in which a positive core attracts the helium atoms from its solvation shell to form a densely, solid-like packed layer. The helium density profile of this interface is much sharper than for electron cavities in helium and gives rise to a lower compressibility of the positive impurity. We believe that this sharper density profile is the reason for the much simpler form of the internal pressure than for electrons.
