Under Ground Cables An Under Ground Cables essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. Under Ground Cables are used, where it is impractical to...
An Under Ground Cables essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. Under Ground Cables are used, where it is impractical to use overhead line...
Types of insulators used in AC distribution system. Overhead line conductors should be supported on the poles or towers with the help of insulators. The insulator provide necessary insulation between the line conductors and...
Voltage regulation When transmission line carries the current, there is a voltage drop in the line due to resistance and inductance of the line. This results, the receiving end voltage VR is less than...
Types of D.C. Generators The magnetic flux in a DC machine is produced by the field coils carry current. The circulating current in the field wingdings produces a magnetic flux, and the phenomenon is...
E.M.F Equation of DC Generator As the armature rotates and cuts the magnetic lines of force, a voltage is generated in its coils. The e.m.f. induces in the conductors according to ‘Faraday’s Law of...
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...
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...
