Time Graded Overcurrent Protection: In this scheme of Time Graded Overcurrent Protection, time discrimination is incorporated. In other words, the time setting of relays is so graded that in the…
Busbar Protection: Busbars and lines are important elements of electric power system and require the immediate attention of protection engineers for safeguards against the possible faults occurring on them. The…
Protection of Transformers: Transformers are static devices, totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However, the consequences of even a rare…
Protective Relay: A Protective Relay is a device that detects the fault and initiates the operation of the circuit breaker to isolate the defective element from the rest of the…
Fuses Definition: Fuses Definition States that : A fuses is a short piece of metal, inserted in the circuit, which melts when excessive current flows through it and thus breaks…
Location of Reactors in Power System: Short circuit current limiting Location of Reactors in Power System may be conÂnected in series with each generator in series with each feeder and…
Bus Bar Arrangement in Power Station: When a number of generators or feeders operating at the same voltage have to be directly connected electrically, bus-bars are used as the common…
Switchgear Equipments: Switchgear covers a wide range of equipment concerned with switching and interrupting currents under both normal and abnormal conditions. It includes switches; fuses, circuit breakers, relays and other…
