Use Hall Effect Measurements to Characterize Materials
Written by Robert Green Engineers have been using Hall effect measurements to characterize materials since Edwin Hall discovered the phenomenon in 1879. The Hall effect is the generation of a voltage, called the Hall voltage, across a sample of a… Read more

Insulating materials in electrical equipment
The reason for using insulating materials is to separate electrically the conducting parts of equipment from each other and from earthed components. Earthed components may include the mechanical casing or structure that is necessary to enable the equipment to be… Read more

Materials with magnetic properties
All materials have magnetic properties. These characteristic properties may be divided into five groups as follows: Diamagnetic Paramagnetic Ferromagnetic Antiferromagnetic Ferrimagnetic Only ferromagnetic and ferrimagnetic materials have properties which are useful in practical applications. Ferromagnetic properties are confined almost entirely… Read more

Comparison Of Cable Insulating Materials
Electrical insulation materials are employed over the metallic conductors of underground cables at all voltage ratings. Polymeric materials are employed as the insulation, but the nature of the polymer may vary with the voltage class. Since paper insulation was used… Read more
