13. Fig. 2 shows the transmission and distribution of power from power station to
consumer. The statements which follow describe the transmission and distribution.
Put the statements in the correct order with the help of the diagram.
Fig. 2
a |
It is fed to distribution substations.
|
|
b |
It is stepped up by a transformer to high voltages for long-distance transmission.
|
|
c |
It is transmitted via the grid to supply points.
|
|
d |
It is distributed to the domestic consumer.
|
|
e |
Electricity is generated at the power station at 25 kV.
|
|
f |
It passes via the switching compound to the grid.
|
|
g |
It is transmitted via overhead or underground cables to intermediate substations.

14. Mark the sequence of stages using appropriate sequence words (first, then, next, after
that, finally) where you think this is helpful. Add the following information to your
statements and make them into a complete description of the process.
1 |
At the main grid supply points power is stepped down to 33 kV for distribution to heavy industry. |
2 |
At intermediate stations power is reduced to 11 kV for light industry. |
3 |
At the distribution substations power is stepped down to 415 V, 3-phase, and 240 V, 1-phase. |
