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
This article covers transformer impedance testing, one of the acceptances tests for new transformers, and a method for routine testing. The results of this test should compare directly to the manufacturer's datasheet. Related: Percentage Impedance of Transformer Application of Transformer Impedance Test The Transformer Impedance Test locates problems within the transformer … [Read more...] about How to Test Percentage Impedance of Transformer?
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 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
A ground fault circuit interrupter (GFCI or GFI) is an inexpensive electrical switchgear device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. Electric shocks can cause severe injury or even death. Even exposure to current as low as 100 ma current for only 2 seconds can cause death. GFCIs … [Read more...] about GFCI (Ground Fault Circuit Interrupter) – Working, Types, Installing and Troubleshooting
