MODERN ZINC OXIDE SURGE ARRESTER



Introduction
The most important matter in a
power system is how to handle a fault condition. In power
system networks we have to maintain the voltage, current
and other network parameters at a specified value .
If an abnormal condition is occurred we
must take precaution against the abnormality to protect
the succeeding elements connected to the network.There
are many modern technique to clear the over voltage
condit ....etc

Abstract
Solid oxide fuel cells (SOFCs), which will be operated at reduced temperature, are becoming a frontier of R and D. These compact size SOFCs will fit well with intermittent loads, of which share in energy system is increasing today, whereas the “conventional SOFCs” will be effectively operated with stationary mode. For such compact size SOFCs, throttle down operation following intermittent loads will be profitable because low current density gives ....etc

Conductive Metal Oxide-CMOx Memory Technology

Introduction

It is a new non volatile memory technology, to be commercialised within two years.

It will take over from today’s NAND flash .

The memory effect of CMOx™ technology is based upon the movement of ionic charge carriers.

APPLICATION OF NITROUS OXIDE IN AUTOMOBILES
INRODUCTION
In modern automobiles, nitrous oxide (often just nitrous or nitro in this context) is sometimes injected into the intake manifold (or just prior to the intake manifold) to increase power: even though the gas itself is not flammable, it delivers more oxygen than atmospheric air by breaking down at elevated temperatures, thus allowing the engine to burn more fuel and air. Additionally, since nitrous oxide is stored as a liquid ....etc

A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc

The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multipulse current (8/20micros) was used to artificially degrade the MOSA. The before and after diagnostic ....etc
