Short Circuit kVA

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 of normal system voltage and short-circuit current at the point of fault expressed …

Percentage Reactance in Power System

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 of the total phase-voltage dropped in the circuit when full-load current is …
