Title: Define the grid.
Course: Introduction to Energy Transmission and Distribution I (20902-36) > Section: Understanding the Electrical Grid

Definition should include

- the grid – transmission network
- difference between transmission and distribution
  - transmission – the process of delivering energy (115 to 500 kV) from generation/production to substation
  - distribution – the process of delivering energy (120 V to 34.5 kV) from substation to the end user
- components of the transmission grid
  - power station
  - step-up transformers
  - switchyard
  - transmission towers
  - transmission lines (overhead and underground)
  - transmission substations
  - regulators
- components of the distribution grid
  - distribution substations
  - step-down transformers
  - breakers/fuses
  - switches
  - distribution lines (overhead and underground)
  - utility poles
  - regulators
  - inverters.

Process/Skill Questions:

- What is the purpose of the step-up transformer? Step-down transformer?
- What are the main differences between transmission grids and distribution grids?
- What is the purpose of a breaker or fuse in the distribution grid?
