1.
Draw the general structure of a modem transmission, distribution and utilization
network
2.
Differentiate between transmission, distribution and utilization substations
3.
Write short notes on the following

Skin effect
(iii)
Galloping lines
(iv)
Ferranti effect
4. Discuss the characteristics of a power system
5. A 20 km transmission line operating at 13.2 kV has just been disconnected from the
source. A lineman could receive a fatal shock if he does not first connect the line to
ground before touching it. Explain?
6. Explain why it is generally advisable to disconnect all electrical appliances when there
is energy shortage
