Hysteresis loss and eddy current losses definition, formula, comparison, ppt presentation material, transformer magnetic losses, principle, applications, damping testing etc
Losses in the transformer are of the order of 1% of its full load kW rating. These losses get converted in the heat thereby the temperature of the windings, core, oil and the tank rises. The heat is dissipated from the...
Equivalent circuit and Phasor diagram of transformers are derived explained clearly.

In this writing, I discuss the history of sulfuric acid preparation. I then talk about physical and chemical properties to illusrate the various ways sulfuric acid can be evaluated experimentally.
First the need of dead-band / dead-time is discussed thoroughly and hazards of short-circuiting in H-Bridge are seen. Finally a circuit to implement and generate dead-band / dead-time is given.
The principle parts of milling machine are given: Base The base of the machine is Grey iron casting accurately machined on its top and bottom surface and serves as a foundation member for all the other parts which...
A humorous, yet all-too-real look into Engineering life.
A comprehensive article covering the history, development and various uses for the carbon arc.
UHT (Ultra High Temperature) processing of milk in an aseptic plant can be broken down into specific unit operations. I'll review the physical processes as a general overview - with a little math.
