Amplidyne is a special-purpose DC generator. It supply large DC currents, precisely controlled, to the large DC motors used to drive heavy physical loads, such as gun turrets and missile launchers. The amplidyne is really a motor and a generator. It consists of a constant-speed AC motor (the prime mover) mechanically coupled to a DC generator, which is wired to function as a … [Read more...] about Amplidyne – Working and Application

Electrical Substation: Equipment, Types, Components & Functions
An electrical substation is an installation with electrical equipment capable of interrupting or establishing electrical circuits and changing the voltage, frequency, or other characteristics of the electrical energy flowing in the circuits. The substation provides interconnection of transmission circuits and transformation between the network of different voltages. The … [Read more...] about Electrical Substation: Equipment, Types, Components & Functions
Transformer Bushing Types : RIP Bushing vs OIP Bushing
Transformer bushing types are categorized based on their material, manufacturing, and design mainly into the following types: OIP (Oil-Impregnated Paper) Bushing RIP (Resin Impregnated Paper) Bushing RIS (Resin Impregnated Synthetic) Bushing Resin Bonded Paper (RBP) Bushing Cast Epoxy Bushing You can read about all other types of electrical bushings in … [Read more...] about Transformer Bushing Types : RIP Bushing vs OIP Bushing
Bundled Conductors in Transmission Lines
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 lines are commonly used to increase electrical capacity and reduce corona and radio noise at voltages … [Read more...] about Bundled Conductors in Transmission Lines
