CALCULATIONS SHORT CIRCUIT CURRENT & KVA – PART – 01 – PERCENTAGE REACTANCE

PERCENTAGE REACTANCE
Percentage reactance is the load phase voltage dropped in the circuit when a full load current is flowing in the system.
Shor circuit current is obtained by multiplying the full load current by 100/%X.
Percentage reactance = [Base kVA / rated kVA] * %X
Where %X of reactance at rated kVA.
