A sinusoidal voltage can be described by the equation: v(t) = VM sin (ωt + Φ) or v(t) = VM cos (ωt + Φ) where v(t) Instantaneous value of the voltage, in volts (V). VM Maximum or peak value of the voltage,
Transformer is very simple and basic part of electrical system and considered most efficient of electrical components of machines. If we consider experimental models which are using superconducting windings then we may talk about achieving the the performance of 99.75 percent as
Transformers Fittings In order to install a medium voltage transformer below is the list of necessary fittings: Plain bi-directional rollers with blocking facilities. Skid base, lifting and jacking lugs Neutral and earthing terminals Rating and terminal marking plates Transformer Thermal Protection Temperature
What is Magnetism? Magnetism is the study of magnetic fields and their effect on materials. The effect is due to unbalanced spin of electrons in atom. It is readily observed every day from the simple magnet that attracts nails and other metals
To best understand the Electromagnetic Induction lets first have a look on two important laws relating to the subject of this article. Lenz’s law is named after a Russian physicist of Baltic German descent Heinrich Lenz in 1834, and it states that,
What is a balun? A Balun is special type of transformer that performs two functions i.e. impedance transformation and balanced to unbalanced transformation. The term balun is a contraction of “balanced to unbalanced transformer” Why do we need a balun? Baluns are
