Three phase to ground fault takes place at locations $${F_1}$$ and $${F_2}$$ in the system shown in the figure. GATE EE 2014 Set 1 Power System Analysis - Symmetrical Components and Symmetrical and Unsymmetrical Faults Question 36 English

If the fault takes place at location $${F_1}$$, then the voltage and the current at bus A are $${V_F1}$$ and $${{\rm I}_{F1}}$$ respectively. If the fault takes place at location $${F_2}$$, then the voltage and the current at bus A are $${V_{F2}}$$ and $${{\rm I}_{F2}}$$ respectively.

The correct statement about voltages and currents during faults at $${F_1}$$ and $${F_2}$$ is

A
$${V_{F1}}$$ leads $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ leads $${{\rm I}_{F2}}$$
B
$${V_{F1}}$$ leads $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ lags $${{\rm I}_{F2}}$$
C
$${V_{F1}}$$ lags $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ leads $${{\rm I}_{F2}}$$
D
$${V_{F1}}$$ $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ lags $${{\rm I}_{F2}}$$
