ARC-FAULT CIRCUIT INTERRUPTER(AFCI)
INTRODUCTION
Annually, 40,000 fires - 300 deaths - over 1,400 injuries
Arcing faults are the major cause of residential fires. In 1994 an insurance company survey of 660 electrical fires indicated that over 33% of these fires were from arcing condition.
An arc fault is the flow of electricity over an unintended path. 
Unwanted arcing generates high temperatures and discharges molten metal that can ignite nearby combustibles such as paper, insulation, vapors, and carpets.
Te ....etc

Introduction:
The plasma welding process was introduced to the welding industry in 1964 as a method of bringing better control to the arc welding process in lower current ranges. Today, plasma retains the original advantages it brought to industry by providing an advanced level of control and accuracy to produce high quality welds in miniature or precision applications and to provide long electrode life for high production requirements.
The plasma process is equally suited to manual and automati ....etc

Abstract :

The case study project is significant since mild steel is used in structure, case hardening, gears, free cutting steels, shafting, forging etc. Mild steel plates were tested for mechanical properties like hardness, tensile strength, yield point etc. Later on the plates were joined by submerged arc welding and the mechanical properties were estimated again. Also weld ability, harden ability, tensile test etc. were conducted for the same result. ....etc

Abstract
A significant percentage of the flux used in submerged are welding gets converted into very fine particles particles
termed as flux dust due to transportation and handling. If these very fine particles are not removed fromt he flux before
welding, it may results ....etc

An Improved Nonlinear STATCOM Control for Electric Arc Furnace Voltage Flicker Mitigation
Abstract
Electric arc furnaces (EAFs) are prevalent in the steel industry to melt iron and scrap steel. EAFs frequently cause large amplitude fluctuations of active and reactive power and are the source of significant power-quality (PQ) disturbances. Static synchronous compensators (STATCOMs) provide a power-electronicbased means of embedded control for reactive power support and PQ improvement. This paper introduces a new nonlinear cont ....etc
