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 38 English

GATE EE 2014 Set 1 Power System Analysis - Symmetrical Components and Symmetrical and Unsymmetrical Faults Question 38 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

$${V_{F1}}$$ leads $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ leads $${{\rm I}_{F2}}$$

$${V_{F1}}$$ leads $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ lags $${{\rm I}_{F2}}$$

$${V_{F1}}$$ lags $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ leads $${{\rm I}_{F2}}$$

$${V_{F1}}$$ $${{\rm I}_{F1}}$$ and $${V_{F2}}$$ lags $${{\rm I}_{F2}}$$

x(t) is nonzero only for $$T_x\;<\;t\;<\;T_x^1$$ , and similarly, y(t) is nonzero only for $$T_y\;<\;t\;<\;T_y^1$$ . Let z(t) be convolution of x(t) and y(t). Which one of the following statements is TRUE?

z(t) can be nonzero over an unbounded interval

z(t) is nonzero for $$t\;<\;T_x+T_y$$

z(t) is zero outside of $$T_x+T_y\;<\;t\;<\;T_x^1+T_y^1$$

z(t) is nonzero for $$t\;>\;T_x^1+T_y^1$$

GATE EE 2014 Set 1 Signals and Systems - Continuous and Discrete Time Signals Question 7 English

$$u\left(t\right)-u\left(t-T\right)+\frac{\left(t-T\right)}Tu\left(t-T\right)-\left(\frac{t-2T}T\right)u\left(t-2T\right)$$

$$u\left(t\right)+\frac tTu\left(t-T\right)-\frac tTu\left(t-2T\right)$$

$$u\left(t\right)-u\left(t-T\right)+\frac{\left(t-T\right)}Tu\left(t\right)-\left(\frac{t-2T}T\right)u\left(t\right)$$

$$u\left(t\right)+\frac{\left(t-T\right)}Tu\left(t-T\right)-2\frac{\left(t-2T\right)}Tu\left(t-2T\right)$$
