Working Principle of DC Generator
Working Principle: An electric generator is based on the principle that whenever flux is cut by a conductor, an e.m.f. is induced which will cause a current to flow if the conductor circuit is...
Construction of DC Generator
An electric generator is a machine that converts mechanical energy into electrical energy. An electric generator is based on the principle that whenever flux is cut by a conductor, an e.m.f. is induced which...
Methods of AC distribution system based on connection scheme
Explain methods of AC distribution system based on connection scheme. The following connection schemes of distribution system are generally employed: Radial System: In a radial system, separate feeders radiate from a single sub-station and feed the...
