Question Paper
List the advantages and limitations of high transmission voltage.
Compare the conductor material (volume) for a 3-phase, 4-wire distribution system with that of a 2-wire D.C. distribution system. State the assumptions made.
Describe briefly the following types of insulators:
Pin type insulator
Suspension type insulator
Explain what is meant by the string efficiency of a suspension insulator consisting of a number of units. What causes the string efficiency to be less than 100 percent?
Explain the phenomenon of corona loss. How can the corona loss be minimised in transmission lines?
Explain the modified Kelvin's law with graphical representation and also describe the limitations.
What is a sag template? Explain how this iS useful for location of towers and stringing of power conductors.
Describe with a neat sketch, the construction of a 3-core belted type cable. Discuss the limitations of such a cable.
5. Find the values of ABCD constants for a medium transmission line with the following configurations (in terms of Z and
Nominal 1t configuration
Nominal T configuration
A single-phase overhead transmission line is delivering 600 kVA load at 2 kV. Its resistance and reactance are 0.18 ohm and 0.36 ohm respectively. Determine the voltage regulation if the load power factor is
0.8 lagging, and
(ii)0.8 leading.
6. State various types of distribution systems and compare their applications.
State the advantages and disadvantages of a 3-wire A.C. distribution system over a 2-wire D.C. distribution system.
7. Write short notes on any two of the following:
Comparison of Cables and Overhead Lines
Capacitance of Single and Multicore Cables
(c)Static and Synchronous Phase Modifiers
Surge Impedance Loading
