A (medium) single phase transmission line 100 km long has the following
Resistance/km = 0.25 2;
Susceptance/km = 14 × 10 siemen;
Reactance/km = 0.8
Receiving end line voltage = 66,000 V
Assuming that the total capacitance of the line is localised at the receiving end alone, determine
(i) the sending end current (ii) the sending end voltage (iii) regulation and (iv) supply power factor.
The line is delivering 15,000 kW at 0.8 power factor lagging. Draw the phasor diagram to illustrate
your calculations.

General Directions: Read the questions carefully and answer (3*10=30marks)
1. Design a summing amplifier by choosing appropriate values of resistors an so that
the output is 5 times the sum of the input voltages. (you are free to use any number
of inputs, the type of op-amp, any value of resistors)
2. Derive the equation for the closed loop gain of the inverting and non-inverting
Amplifier using appropriate circuit diagrams.
3. Determine the values read by the measuring devices using appropriate formulae
