Question

The reactance of a generator designated 'x' is given as 0.20 pu based on the generator's name plate rating of 18 k, 500 MVA. If the base for calculations is changed to 20 kV, 100 MVA, the generator reactance X on new base will be (in pu) : Select one: a. 0.05 pu b. 0.0324 pu c. 0.0405 pu d. 0.52 pu

Step 1

Base impedance (Zbase) = (Voltage base)^2 / (MVA base) Zbase = (18kV)^2 / 500MVA Zbase = 324kV^2 / 500MVA Zbase = 0.648 pu Show more…
