Six major items(component) in a power system layout

1. Generator: this is the main source of supply in any power station
2. Transformer: this is used in each area or geolocation to step up or step down voltages for the suitable transmission.
3. Transmission line: it is the thick wire or conductor used to pass electricity from generating station to transformer for use.
4. Lightening arrestors: it protect the other components from thunder strike and other relative dangers
5. Insulators: it is used to cover the conductors outer body in order to prevent shock.
6. Breakers: it is a component mostly found at the entrance of a building, to take electricity for consumers use.

State eight (8) advantages of hydropower plant.

1. It’s renewable: it can be regain back after usage since it main source is water.
2. It is clean and no pollution: among all other type of generating system the hydropower station produces no  pollution whatsoever to the environment
3. Flexibility: tapping is encouraged and it’s also used for bulk transmission of electricity for both large and small consumers
4. It requires no fuel i.e little or no running cost as water is the main source of energy
5. It serve many purposes such as control floods and use in  irrigation system e.t.c
6. It requires little maintenance
7. Reliability: it is highly reliable and trusted  kind of power system.
8. It is robust and have a longer life
9. Starter is not needed i.e it can be put into service instantly without not wasting time.
10. It is comparatively simple in construction
11. Although it need a well skilled personnel to do the work a few skilled personnel can do the work well.
12. No losses are incurred when at a standstill.
13. Can be stored up easily and can be used for peaks
