Step 1
X1 = 0.1 * Z_base X1 = 0.1 * (375000 VA / (480 V)^2) X1 = 0.1 * 15.625 X1 = 1.5625 ohms Show more…

'5. A 3-phase, 50 Hz, star-connected, 1000 KVA, 2300V alternator gives a short-circuit current of 400 A for a certain field excitation. With the same excitation, the open-circuit voltage was 1328 V (phase value). The d.c. resistance between two lines is 0.412 Q. Find effective armature resistance (b) synchronous reactance (c) the full-load voltage regulation at 0.8 p.f: lagging: (Ans. 0.309@/phase (b) 3.319 (c) 49.6%'

A 50 MVA, 11 kV, three-phase alternator was subjected to different types of faults. The fault currents were: 1870 Amps for three-phase fault, 2590 Amps for L-L fault, and 4130 Amps for L-G fault. The alternator neutral is solidly grounded. Find the three sequence reactances of the alternator.

A three-phase $a b c$-sequence wye-connected source with $\mathbf{V}_{a n}=220 / 0^{\circ} \mathrm{V}$ rms supplies power to a wye-connected load that consumes $50 \mathrm{kW}$ of power in each phase at a pf of 0.8 lagging. Three capacitors are found that each have an impedance of $-j 2.0 \Omega,$ and they are connected in parallel with the load in a wye configuration. Determine the power factor of the combined load as seen by the source.
