  • Quantitative study on the aging of kraft paper in vegetable oils

    Interest in using vegetable oils as dielectric coolants in power transformers dates back to the early studies on linseed- and castor- based fluids as possible replacements of mineral oil. However, interest in vegetable oils was lost due to their high viscosity and their tendency to oxidize. But, in the early 1990s and due to environmental concerns, the interest in dielectric fluids based on vegetable esters re-emerged. As a result, two vegetable ester- based oils were developed, namely, BIOTEMP, developed by ABB, and FR3®, developed by Cooper Power Systems.

  • Design of a high-power wide-band balun for the high-frequency region

    A balun is a device for matching an unbalanced line to a balanced load. Described here is a balun with a cw (continuous wave) rating, with matched load, of 67.5 kva (kilovolt-amperes) over the frequency range from 2 to 30 mc (megacycles). A transmission-line-type design along with a newly developed ferrite core material and special cooling techniques have been used to achieve this wide bandwidth and high-power capabilities in a small size. A description of the unit and performance test results are included.

  • A highly integrated, mass produced battery module as basis for various EV and HEV systems.

    The battery system is the key component in a full electric or a plug-in electric vehicle. Important aspects are cost, package, safety, performance and durability. With a modular design the fundamental requirements can be fulfilled at a sub-level. Providing easy and appropriate interfaces all special issues can be solved efficient on system level. Such a module can be mass produced even in a time where a high diversification in systems can be seen in the test fleets and prototypes. The selected cell is a basis on which a battery system is built. In the case of electric vehicles specific energy is still a very important issue. So is the thermal management as temperature influences performance and life time. In the design process of Akasol an effective thermal management with a temperature imbalance of less than 1°C within a module in a standard cycle was achieved. The actual modules have an energy density of 130 Wh/kg and can be easily configured to full EV systems.

  • Radiological safety during maintenance of the primary heat transfer system of the ITER plant

    The primary heat transfer system (PHTS) of the ITER plant is devoted to the heat removal from different plasma facing components: the first wall, the blanket, the divertor and the vacuum vessel. The system requires a scheduled or regular maintenance that involve component checking and changing, and a special maintenance that has a non periodic nature. During the maintenance operations some shielding barrier has to be partly or completely removed and workers are likely to be exposed to an unusual radiological dose. In the present work the occupational radiation exposure (ORE) for the maintenance activities performed at the PHTS has been assessed. The problem of the activated corrosion product (ACP) transport assessment inside the coolant has been faced and solved with the computer code PACTOLE. The working procedure protocols have been taken from the fission PWR plant experience. The shielding effectiveness of the PHTS components has been evaluated with a well tested computer code. The final result presented in the work is the collective dose for regular and special maintenance at the ITER PHTS, compared with typical data coming from the PWR operational experience.

  • A New Cooling Technology for the Cooling of HTS Magnets

    For decades, the cooling method of conventional superconducting magnets has been "pool-boiling" in liquid cryogen. The commercial availability of HTS superconductors with an operating temperature in the 20 K region however calls for a new cooling strategy due to cost and availability of the new coolants involved. In this paper an alternative to the traditional bath-cooling of magnets with liquid helium is presented by employing a network of dedicated cooling tube structures capable of satisfying the different operating conditions of the magnet as well as the conductor stability requirements. The proposed closed-loop cooling tube concept based on the thermosiphon principle without loss of coolants and minimizing the coolant inventory while at the same time requiring no operator intervention has been tested. The design and the test results are discussed.

  • A thermoelectric generation waste heat recovery system using engine coolant for light-duty ICE vehicles

    We have proposed and developed a low temperature thermoelectric generator using engine water coolant of light-duty vehicles. Experimental results from test vehicle, of which engine size is about 2.0 liters, show that fabricated prototype Thermoelectric Generator generates more than 75W for driving condition of 80 km/hour, and output power is about 28Watt during idle condition. The proposed TEG can replace conventional radiator without additional water pumps or mechanical devices except for basic components of legacy water cooling system of radiator.

  • Experiment and simulation study on cold start of automotive PEMFC

    Different methods to improve the cold start of a stack were studied under the different conditions using experiments and simulations. The heat storage period of the stack was analyzed contrastively with /without heat storage. The stack not sealed by heat storage material needs merely 3 hours and 7 hours to drop to 0°C from initial 80°C in the ambient condition of 20°C, respectively, whereas the heat storage period of the stack sealed by the thick polystyrene and vacuum insulation plate with thickness 20 mm are 26 hours and 34.8 hours. The stack was heated by coolant using the different power of electric heater. When the initial temperature of the coolant was 20°C and 40°C and the power of the electric heater was 2.4 KW, it took 323 s and 165 s to heat the stack up to 0°C. The larger the power of electric heater is, the shorter the time of the stack's temperature which rises to 0°C is. In a word, it is the proper plan is to employ both heat storage and electric heating.

  • Thermal and electrical experimental characterization of Ethylene Glycol and water mixture nanofluids for a 400w Proton Exchange Membrane Fuel Cell

    Nanofluid is an emerging technology in heat transfer study. The effect of nanofluids as a cooling medium in liquid cooled Proton Exchange Membrane Fuel Cell (PEMFC) is studied. Nanofluids with 0.1% and 0.5% volume concentration of Al<sub>2</sub>O<sub>3</sub> are dispersed in base fluid of 50:50 mixture of Ethylene Glycol and water were analyzed experimentally. A rated power of 400 W liquid cooled PEMFC was used to verify the findings. The result showed that insignificant improvement in performance of PEMFC with nanofluids through polarization curve findings, perhaps due to the lower wattage of PEMFC used. The advantage of nanofluids utilization in PEMFC might be visible in higher wattage of PEMFC due to higher working fluid temperature. Higher thermal conductivity of nanofluid at higher temperature is expected to give advantage in terms of polarization curve of a PEMFC. However, the thermal performance is improved through the heat transfer rate increment of 68.5 % and 46 % for both 0.5 % of Al<sub>2</sub>O<sub>3</sub> nanofluid and 0.1 % of Al<sub>2</sub>O<sub>3</sub> nanofluid respectively.

  • Retrofilling aging transformers with natural ester based dielectric coolant for safety and life extension

    The number of mineral oil filled distribution and substation transformers at cement and mineral extraction plants that are approaching the end of their normal life expectancy is increasing. A proposed method of extending their remaining life is possible by retrofilling with a natural ester dielectric coolant. Additional benefits include reduced fire and environmental risks if the unit fails or when it is decommissioned. This paper reports on tests of miscibility and compatibility of mixtures of the two types of dielectric coolants. The paper also discusses field experience with retrofilling mineral oil-filled distribution and power transformers with a natural ester. Finally, results of an accelerated paper aging retrofill study are presented. The data collected to date suggests that the aging rate of the paper is significantly improved. Other benefits indicated by data include an increase in the fire point by approximately 200/spl deg/C, a significant reduction in the moisture content of the insulation paper, the probable elimination of bubble formation due to sudden overload, and the elimination of oil sludge formation. The increase in the dielectric coolant fire point to over 300/spl deg/C essentially eliminates the risk of oil pool fires by arcing in the event of internal fault arcing.
