GATE Electrical 2014 Set 3 | Question: 6
The line $A$ to neutral voltage is $10\angle 15^\circ$ for a balanced three phase star-connected load with phase sequence $ABC$. The voltage of line $B$ with respect to line $C$ is given by $10\sqrt{3}\angle 105^\circ$ $10\angle 105^\circ$ $10\sqrt{3}\angle -75^\circ$ $-10\sqrt{3}\angle 90^\circ$
The line $A$ to neutral voltage is $10\angle 15^\circ$ for a balanced three phase star-connected load with phase sequence $ABC$. The voltage of line $B$ with respect to ...

GATE Electrical 2016 Set 1 | Question: 41
A $30 MVA$, $3$-phase, $50 Hz$, $13.8 kV$, star-connected synchronous generator has positive, negative and zero sequence reactances, $15\%$, $15\%$ and $5\%$ respectively. A reactance $(X_{n})$ is connected between the neutral of the ... The value of $X_{n}$ (in p.u.) that will limit the positive sequence generator current to $4270 \: A$ is ________.
