Abstract

In order to qualify the electrical insulation design of future HTS cables installed in the electric grid, a number of high voltage qualification tests are generally performed in the laboratory on either single-phase model cables and/or actual three-phase cable samples. Prior to installation of the 200-rn Triax HTS cable at the American Electric Power Bixby substation near Columbus, Ohio, in September, 2006, such tests were conducted on both singlephase model cables made at ORNL and tri-axial cable sections cut off from cable made on a production run. The three-phase tri-axial design provides some specific testing challenges since the ground shield and three phases are concentric about a central former with each phase separated by dielectric tape insulation immersed in liquid nitrogen. The samples were successfully tested and qualified for partial discharge inception, ac withstand, and lightning impulse where voltage is applied to one phase with the other phases grounded. In addition one of the phase pairs was tested for dc withstand as a "worst case" scenario to simulate the effect of VLF (Very Low Frequency) tests on the actual cable installed at the Bixby site. The model and prototype cables will be described and the high voltage test results summarized. [ABSTRACT FROM AUTHOR]

Abstract

The article focuses on the development of a novel high-temperature-resistant coatings being conducted by researchers with the Ohio State University in Columbus. The coatings will be made of yttria-stabilized zirconia containing aluminum oxide (Al2O3) and titanium dioxide (TiO2 which has the ability to combat molten glass deterioration and chemically convert sand and particles. It adds that the technology will be beneficial to airplane engine blade manufacturers.

3. Bill Curbing Asbestos Suits Signed Into Law By Ohio Gov.

Subjects
HEAT resistant materials, REFERENDUM, ACTIONS & defenses (Law), COMPUTERS in systems design
Abstract

Ohio GOP Gov. Bob Taft signed a measure making the state the first in the nation to require individuals exposed to asbestos to prove that exposure and meet a set medical threshold to proceed with a lawsuit. Otherwise healthy companies have gone bankrupt because of asbestos lawsuits. The bill will become law in 90 days and is expected to face legal challenge. Some asbestos lawyers have mulled financing a referendum petition campaign asking voters to repeal the law. Individuals seeking to sue or already in the system would have to demonstrate either they have developed an asbestos-related lung cancer or suffered a significant loss of lung function.
