Chapter 2 Magnetic Materials and Their Characteristics

power equipment. Improvements in the Ni-Fe alloys were achieved by high temperature anneals in hydrogen atmosphere, as first reported by Yensen. The next improvement was done by using grain-oriented material and annealing it, in a magnetic field, which was also in a hydrogen atmosphere. This work was done by Kelsall and Bozorth.

Remarks on line capacitance 1. The greater the spacing between the phases of a transmission line, the lower the capacitance of the line. – Since the phases of a high-voltage overhead transmission line must be spaced further apart to ensure proper insulation, a high-voltage line will have a lower capacitance than a low-voltage line.

What is Dielectric Constant? - Matmatch

The capacitance of a capacitor depends on the permittivity ε of the dielectric layer as per the formula below `C=varepsilonleft(frac{A}{d}right)` Where `A` is the area of the capacitor, and `d` is the distance between the two conductive plates in the capacitor. When vacuum is used as a dielectric, the capacitance is given by
