Estimation of sulphur compounds in transformer oil

2011 International Conference on Power and Energy Systems, 2011

Corrosion of copper conductors in transformers is a major problem affecting the paper-oil insulation, ultimately leading to failure of transformers. Hence there is a growing concern on the issues like quality of oil, transformer design and its service conditions. Sulphur compounds are believed to be responsible for formation of semi conducting copper sulphide in paper insulation. This paper discusses the ...

  • Estimation of sulphur compounds in transformer oil

    Corrosion of copper conductors in transformers is a major problem affecting the paper-oil insulation, ultimately leading to failure of transformers. Hence there is a growing concern on the issues like quality of oil, transformer design and its service conditions. Sulphur compounds are believed to be responsible for formation of semi conducting copper sulphide in paper insulation. This paper discusses the results of transformer oil drawn from different transformers of Power utilities in terms of total sulphur, mercaptan sulphur and DGA.

  • Novel recording media: Fe<inf>14</inf>R<inf>2</inf>B particles

    Conditions for hydrogen absorption and methods of preparing fine particles of Fe14R2B (R=Nd,Y,Ce) via hydriding are described. Hydrogen absorption and desorption are of the above-critical type (no phase segregation). Sub-micron sized particles can be prepared by repeated desorption cycles, making use of the decrepitation inherent in the hydriding process. The neodymium compound decomposes under hydrogen at 650°C and 107Pa, forming NdH2, Fe, and Fe-B. Recombination is achieved by prolonged heating at 1100°C in a vacuum. Vibrating sample magnetometry and Mössbauer spectroscopy were used to measure the magnetic properties of the material before and after hydriding, together with scanning electron microscope observations of the particles formed.

  • Reentrant behavior in the temperature dependence of metamagnetic transitions in single crystal Nd/sub 6/Fe/sub 13-x/Al/sub 1+x/

    Nd/sub 6/Fe/sub 13-x/Al/sub 1+x/, (/spl delta/) is a complex antiferromagnet with a Neel temperature that ranges from /spl sim/250 K to /spl sim/350 K. Studies of polycrystalline samples of the Nd compound have shown that the material undergoes a series of metamagnetic transitions as a function of magnetic field. In the present study, single crystals of /spl delta/ have been grown and characterized. Low temperature magnetization studies demonstrate that there are a number of competing magnetic interactions in the material, which have different temperature dependencies. As a result, for a narrow range of fields, the /spl delta/ crystals exhibit unique reentrant magnetization versus temperature behavior.

  • Monolithic, self-frequency doubled, neodymium-doped yttrium aluminium borate green laser with low intensity noise

    A monolithic, self-frequency-doubled green laser is fabricated from neodymium- doped yttrium aluminium borate. The threshold pump power for green output is less than 10 mW, and up to 20 mW of green output ( lambda =531 nm) in a TEM/sub 00/ mode is generated when pumped by a 1 W GaAlAs laser diode. The green output is free of large-amplitude fluctuations with a relative intensity noise of -154 dB/Hz.<<ETX>>

  • Efficient fibre-coupled laser diode end-pumped NYAB laser

    Under optimum pump conditions, 60 mW of green laser output corresponding to a conversion efficiency 6% was obtained from a self-frequency-doubling NYAB crystal when pumped by a 1 W fibre-coupled laser diode. The prospect of higher conversion efficiency is also discussed.

  • Investigation of interface delamination in a SO8 package under reflow

    In the semiconductor industry, efficient and effective reliability qualification is very critical. In order to investigate the moisture effect for nonhermetic packages, reliability test such as preconditioning is designed and characterized. Interface delamination is a very common moisture-related failure mode. This is the comprehensive results from coefficient of thermal expansion (CTE) mismatch and hygroscopic swelling mismatch between different materials, degradation of materials and adhesion strength, and large vapor pressure buildup in high temperature. In this paper, the finite element analysis (FEA) modeling is conducted to study the interface delamination of the SO8 package during reflow with and without moisture. The moisture diffusion simulation is firstly conducted using the thermal-moisture analogy. Then the vapor pressure is calculated based on the moisture distribution and steam table. Finally, the equivalent CTE method is used to simulate the stress, which includes the CTE mismatch induced stress, hygroscopic stress and vapor pressure induced stress. The impact of 4 parameters are studied, die attach (DA) material, bond line thickness (BLT), DA epoxy coverage, and reflow with and without moisture. Totally 54 simulation legs are generated through the design of experiment (DoE) for the 4 variables with different levels. Simulation results show that the stresses in DA epoxy and mold compound increase when subjected to reflow with moisture compared with the pure reflow without moisture. Thin BLT might increase the risk of interface delamination between DA epoxy and die attach pad (DAP), mold compound and lead frame. Full DA coverage is not the best case to obtain the lowest interface stress and avoid interface delamination.

  • Feasibility of Nd Substitution in (La, Nd)(Fe, Si)<sub>13</sub>Magnetocaloric Compound Obtained by the Reduction-Diffusion Process

    Quaternary magnetocaloric compound La1-xNdxFe11.3Si1.7was synthesized via the so-called reduction-diffusion (RD) process. The RD process was carried out at 1423 K, using Ca as the reducing agent and La and Nd oxides as the precursors to form, together with iron and silicon powder, the desired cubic NaZn13-type structure. The main purpose was to study the interchange of La and Nd in terms of process yield, crystal structure parameters and typical magnetic transition temperature [Curie temperature (Tc)] associated with the magnetocaloric effect. Microstructural characterization by scanning electron microscopy associated with microprobe energy dispersive spectroscopy and backscattered electron imaging was used to identify morphology and particle size of reaction products, as well as the extent of diffusion reactions. Structural characterization results obtained by X-ray diffraction technique associated with Rietveld refinements show the possibility to obtain almost single-phase La1-xNdxFe11.3Si1.7, for which x was varied from 0 to 0.5, with reminiscent α-iron phase below 10 wt%. Moreover, the Tc of all obtained alloys were inferred from differential scanning calorimetry curves, showing that Nd is an effective alloying element to tune the working temperature in the near-room- temperature magnetic refrigeration.
