Title: Describe the electric distribution network.
Course: Energy and Power (20101-18) > Section: Exploring Electric Transmission, Distribution, and Storage

Description should include

- a definition of distribution―the delivery of electricity via lines (e.g., primary voltages from 2400 v to 34,520 v; secondary voltages from 120 v to 480 v) from substations to consumers
- identification of basic symbols
- components of distribution, such as
  - substation (e.g., step-down transformers, switches, breakers, buss work)
  - voltage regulators
  - poles
  - distribution lines (e.g., overhead and underground)
  - protective devices (e.g., fuses, breakers, reclosers, cut-outs, grounding system)
  - services
  - meters
  - behind-the-meter distributed generation.

Process/Skill Questions:

- Where might underground lines be used instead of overhead lines?
- What is the difference between a fuse and a breaker?
- How are electric meters used in billing for energy consumption?
- What is an electrical substation and its purpose?
- How can a one-line diagram identify the parts of a system?
- Why is it important to ground electrical current?
- What is net metering?
