Leakage Current on Porcelain and Silicone Insulators Under Sea or Light Industrial Pollution

IEEE Transactions on Power Delivery, 2011
The leakage current on heavily polluted silicone rubber insulators is usually smaller than on similarly polluted porcelain insulators. In this paper, results are presented that show that under light contamination, the currents on the two types of ...

A solution of the porcelain insulator problem

Journal of the American Institute of Electrical Engineers, 1921
MANY YEARS ago porcelain insulators on transmission lines began to crack in great numbers. In the earlier cases a few disks in many strings had cracked before the transmission engineers had discovered the condition. Indeed, there was at that time no reason to believe that insulators would deteriorate in any way.

The impulse characteristics of porcelain insulators

Journal of the Institution of Electrical Engineers - Part I: General, 1941
This report deals with the flashover voltage of insulators and gaps subjected to impulse voltages of different wave-shapes, with the relation between crest voltage and time to flashover at voltages above the minimum required for flashover, with breakdown while the voltage is rising rapidly, with the simultaneous application of impulse and alternating ...

Vacuum Evaporation of Porcelain Mixture in Production of Porcelain Insulators

Glass and Ceramics, 2005
The process of vacuum evaporation of porcelain mixtures on vacuum presses and the ways for improving the production of porcelain insulators are considered. A calculation of unit molding pressure is proposed; the pressure distribution along the press and depending on the moisture of the mixture is indicated.

Investigation of Porcelain Insulators at High Altitudes

Transactions of the American Institute of Electrical Engineers, 1946
The use of high voltage apparatus in military aircraft made it necessary to obtain flashover data on capacitor bushings at altitudes up to 50,000 feet. Some of the more pertinent data are presented in this paper which gives a-c and d-c flashover voltages for porcelain bushings having spacings of 5/8 inch to 2 7/8 inches from cap to ring. The tests were

The production of porcelain for electrical insulation — IV

Journal of the American Institute of Electrical Engineers, 1923
This article contains several excerpts taken from papers presented at recent meetings of the San Francisco and Los Angeles Sections by Dr. Joseph A. Jeffery on “Modern Methods of Firing High-Voltage Porcelain.” The pyrochemical reactions which take place during firing have been described1.
