The combination of more than one conductor per phase in parallel suitably spaced from each other used in an overhead transmission line is defined as a bundled conductor. The individual conductor in a bundle is defined as a sub conductor. Bundled conductors in transmission … [Read more...] about Bundled Conductors in Transmission Lines

Comparison between Induction Motor and Transformer
An induction motor may be considered to be a transformer with a rotating short-circuited secondary. The stator winding corresponds to the transformer primary and the rotor winding to the transformer secondary. However, the following differences between the two are worth … [Read more...] about Comparison between Induction Motor and Transformer

Load Forecasting – Purpose, Classification and Procedure
What is Load Forecasting? Electrical energy cannot currently be stored in large amounts. It has to be generated whenever there is a demand for it. It is, therefore, imperative for the electric power utilities that the load on their systems should be estimated in advance. The … [Read more...] about Load Forecasting – Purpose, Classification and Procedure
Working Principle of Alternator
The machine which produces 3 phase power from mechanical power is called an alternator or synchronous generator. The working of an alternator is based on the principle that when the flux linking a conductor changes, an emf is induced in the conductor. Alternators are the … [Read more...] about Working Principle of Alternator
4 Advantages of Stationary Armature in Alternator
An alternator operates on the same fundamental principle of electromagnetic induction as a DC generator i.e., when the flux linking a conductor changes, an e.m.f. is induced in the conductor. Like a DC generator, an alternator also has an armature winding and a field winding. … [Read more...] about 4 Advantages of Stationary Armature in Alternator

(D) distributed winding. Check Answer A 17. Symmetrical waveform does not … [Read more...] about Objective Questions on Alternators | Part 2
Armature Reaction in Alternator
Armature reaction in alternator is the effect of armature flux on the field flux (i. e., rotor ampere-turns). Read this article to learn more. We have already discussed the effect of armature reaction on the air gap flux in DC Motor and DC Generator in previous articles. … [Read more...] about Armature Reaction in Alternator
