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 heavy current (called short circuit current) flows through the equipment, causing … (Read More)

Percentage Reactance in Power System: The Percentage Reactance in Power System of generators, transformers, reactors etc. is usually expressed in percentage reactance to permit rapid short circuit calculations. The percentage reactance of a circuit is defined as under : It is the percentage … (Read More)

Short Circuit kVA: Although the potential at the point of fault is zero, it is a normal practice to express the short-circuit current in terms of Short Circuit kVA based on the normal system voltage at the point of fault. The product … (Read More)

Location of Reactors in Power System: Short circuit current limiting Location of Reactors in Power System may be con­nected in series with each generator in series with each feeder and in bus-bars. No definite statement can be given as to which one … (Read More)
