Types of Fuses: Fuse is the simplest current interrupting device for protection against excessive currents. Since the invention of first fuse by Edison, several improvements have been made and now-a-days,…
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…
Analysis of Unsymmetrical Faults: In the Analysis of Unsymmetrical Faults, the following assumptions will be made : The generated e.m.f. system is of positive sequence only. No current flows in…
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…
Symmetrical Faults on 3 Phase System: Most of the Symmetrical Faults on 3 Phase System on the power system lead to a short-circuit condition. When such a condition occurs, a…
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…
Switchgear Definition: Switchgear Definition status that, The apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. The switchgear equipment is essentially concerned with…
