Course: Energy and Power (20101-18) > Section: Transmitting Electricity

Distinction should include the following lines and their uses:

- 500-765 kv, used for bulk transmission (e.g., substation to substation)
- 115-230 kv, used for industrial applications (e.g., paper mill, data center, computer server farm)
- 69-115 kv, used for commercial and residential substations (e.g., shopping centers, neighborhoods).

Process/Skill Questions:

- What are some resources for determining appropriate line size?
- What does the size of the transmission line have to do with the amount of energy being transferred?
- Why do industrial applications require larger lines than residential applications?
