GATE Electrical 2014 Set 1 | Question: 40
A distribution feeder of $1\:km$ length having resistance, but negligible reactance, is fed from both the ends by $400V$, $50\:Hz$ balanced sources. Both voltage sources $S_1$ and $S_2$ are in phase. The feeder supplies concentrated loads of unity power factor as shown in the figure. ... $25\:A$ $50\:A$ and $50\:A$ $25\:A$ and $75\:A$ $0\:A$ and $100\:A$

GATE Electrical 2014 Set 1 | Question: 15
Three-phase to ground fault takes place at locations $F_1$ and $F_2$ in the system shown in the figure If the fault takes place at location $F_1$, then the voltage and the current at bus $A$ are $V_{F1}$ and $I_{F1}$ respectively. If the fault takes place at location ... $I_{F1}$ and $V_{F2}$ leads $I_{F2}$ $V_{F1}$ lags $I_{F1}$ and $V_{F2}$ lags $I_{F2}$
