MHD Generator Working Principle: In thermal generation of electric energy, the heat released by the fuel is converted to rotational mechanical energy by means of a thermocycle. The Modern Power System…
Polyphase Circuits Articles: Polyphase System: In an ac system it is possible to connect two or more number of individual circuits to a common polyphase source. Though it is possible…
Loss of Excitation Protection in Generator: Loss of excitation protection in generator can endanger the generator or the connected system or both. It is caused by accidental tripping of field…
Generator Inter Turn Fault Protection: Merz-Price circulating current protection system does not provide protection against turn-to-turn faults (short circuits between the turns) on the same phase winding of the stator…
Microprocessor Based Digital Relay: With the fast development in large scale integrated (LSI) technology, sophisticated and fast microprocessors are now available. With the rapid growth of modern complex large power…
Amplidyne (Rotary Amplifier) - Definition, Construction, Connection Diagram, Workings and Applications: The amplidyne is a rotary amplifier in which a small amount of power supplied to excite the field is…
Thyristorised Control of DC Electric Traction Motor: The modern trend is towards the use of dc motors (both separately excited and dc series motors) equipped with thyristor chopper control. The…
Interference in Telecommunication Circuit in Electric Traction: In all traction systems track is used as a return path for the current. Some part of the current flows through the track…
