Chapter 1, Problem 1.1P
Broadly speaking, what are the two main objectives of electrical systems?
Expert Solution & Answer
To determine
To discuss:
The two main objectives of electrical systems.
Explanation of Solution
The two main objectives of the electrical systems are
- The aim of an electrical system is to collect, save, alter, transfer and exhibit the information.
- Another aim of the electrical system is to generate, transmit, convert, distribute and store energy in various forms.
Energy is generated at the far stations because of several reasons like availability of the raw material, manpower, land and many more. It is generated at low voltage and then the voltage is raised as the losses are lesser in case of high voltages. To distribute it to the loads, the voltage is again stepped down as per the load requirement. This stepping up and stepping down of energy is done with the help of a device called transformer. Storing, processing and transfer of information is also a very essential part of an electrical system.
