Arcing Faults in Electrical Equipment

IEEE Transactions on Industry Applications, 2009
Electrical incidents that result in significant injuries to people are often the result of substantially unconstrained free-burning arcing fault currents within electrical equipment. It is necessary to understand the nature of these arcs and be able to quantify the parameters before it is possible to really comprehend what is actually happening inside ...

Electric welding by the carbon arc

Journal of the A.I.E.E., 1930
This paper discusses the butt welding of steel sheets by the carbon arc process. It explains first that autogenous welding is divided into two main classes, viz., gas and electric; that electric arc welding is divided into two classes, viz., metallic and carbon arc. Gas and metallic arc welding in general require beveling of plates for butt welds while

Identification of the electric arc of a furnace

1997
This study allows comparing two competitive modelling techniques to identify the electric arc dynamics of a furnace. The first technique relies on a linear kRX model whereas the second one relies on a non linear ARX model built from a MLP neural network.

Compressive strength and durability properties of roller-compacted concrete pavement containing electric arc furnace slag aggregate and fly ash

Construction and Building Materials, 2018
This study investigates the effects of electric arc furnace (EAF) slag aggregate and fly ash on compressive strength and durability properties (i.e. water absorption, abrasion resistance, and sulfate resistance) of roller-compacted concrete pavement ...

Flames from electric arcs

Journal of the A.I.E.E., 1929
The origin of flames from arcs is considered. Their low dielectric strength is attributed to ionization, and their rate of recovery of normal dielectric strength is computed. The large influence of temperature is brought out. Computations are given and experiments described which show how flames can be reduced by passing the arc gases through narrow ...

Enhancement of Electric Arc Furnace Dust by Recycling to Electric Arc Furnace

Journal of Environmental Engineering, 2002
Electric arc furnace (EAF) dust is a hazardous waste product of the steelmaking industry with a high concentration of heavy metals, especially Zn and Pb. Existing treatment processes are industrially viable only when the zinc content is sufficiently high. In this research we present an industrial-scale process to enhance EAF dust by recycling it to the

ELECTRIC ARC WELDING

Journal of the American Medical Association, 1941
In the fabrication of heavier metal products, welding already has extensively replaced bolts and rivets. Automobiles, trucks, ships, tanks, refrigerators, bridges and road machinery are representative of products now manufactured with welding as the chief means for uniting metallic parts.
