Resistance Measurements and Interpretations Relating to Flashover
of Artificially Contaminated Ceramic Insulator Strings
Abstract
The flashover of insulator strings occurring at normal working voltages under contaminated/polluted conditions, obviously deserves serious consideration. Though much researchhas been gone into pollution-induced flashover phenomena but grey areas still exist in our knowledge.In the present experimental study the breakdown (flashover) voltages across gaps on insulatortop surfaces and gaps ....etc

ABSTRACT
A long flashover arrester (LFA), which comprises of three flashover modules using the creeping discharge effect, is described in this paper. In this design, the total arrester stressing voltage is applied simultaneously to all of the three modules so that the voltage-time characteristics of the arresters are improved. It assured reliable protection of medium voltage (e.g., 10kv) over head power line against both ....etc

ABSTRACT
This paper provides an introduction to silicon-on-insulator (SOI) technology and the operating principles of high-voltage SOI devices, reviews the performance of the available SOI switching devices in comparison with standard silicon devices, discusses the reasoning behind the use of SOI technology in power applications and covers the most advanced novel power SOI devices proposed to date. The impact of SOI technology on power integrated circuits (PICs) and the problems associated with the integration of high-voltag ....etc

Silicon on insulator technology (SOI) refers to the use of a layered silicon-insulator-silicon substrate in place of conventional silicon substrates in semiconductor manufacturing, especially microelectronics, to reduce parasitic device capacitance and thereby improving performance SOI-based devices differ from conventional silicon-built devices in that the silicon junction is above an electrical insulator, typically silicon dioxide or (less commonly) sapphire. The choice of insulator depends largely on intended application, with sapphire being ....etc

ABSTRACT
Transparent electronics is an emerging science and technology field focused on producing ‘invisible’ electronic circuitry and opto-electronic devices. Applications include consumer electronics, new energy sources, and transportation; for example, automobile windshields could transmit visual information to the driver. Glass in almost any setting could also double as an electronic device, possibly improving security systems or offering transparent displays. In a similar vein, windows could be used ....etc

Lightning Protection Using LFA-M

Introduction
A new simple, effective and inexpensive method for lightning protection of medium voltage overhead distribution line is using long flashover arresters (LFA). A new long flashover arrester model has been developed.

It is designated as LFA-M. It offers great number of technical and economical advantages. The important feature of this modular long flashover arrester (LFA-M) is that it can be applied for lightning protection of overhead distribution line against both induced overvoltages and dire ....etc

Abstract
Organic thin-film transistors OTFTs have received considerable attention recently because they can be fabricated at reduced temperature and potentially reduced cost compared to hydrogenated amorphous silicon thin-film transistors. Low fabrication temperature allows a wide range of substrate possibilities and makes OTFTs an attractive technology for many low-cost electronics applications, particularly those that require or may benefit from flexible polymeric substrates such as rf identification tags, smart cards ....etc
