TRAINING COURSE:
Distribution
Course Category: Transmission and Distribution
Course description: The purpose of this course is to teach transmission and distribution (T&D) personnel to recognize the basic elements in a distribution system and to understand, in general, how each element works. The course also introduces basic protective devices and the process of sectionalizing. At the conclusion of this course, participants should know how to recognize transformers, voltage regulators, and capacitors. They should also have a basic understanding of how these devices work. Participants should also be able to identify basic protective devices used on distribution systems to protect the system and its components from damage and its customers from outages. And participants should have a basic understanding of how distribution systems are laid out.
Course syllabus:
- Overview of a Distribution System
- Define the term “distribution system” as it relates to this course
- List the basic components that make up a distribution system
- Explain the basic difference between primary distribution voltage and secondary distribution voltage
- Transformers
- Define the term “transformer”
-Explain, in general terms, how a transformer works - Given a simplified diagram, identify the basic elements common to most transformers
- Recognize and identify pole top, pad-mounted, and subsurface transformers
- Voltage Regulators and Capacitor
- Define the term “voltage regulator”
- Identify the electrical and physical elements that make up a typical voltage regulator
-Explain in general terms, how a voltage regulator works - Define the term “capacitor”
-Explain, in general terms, how a capacitor works - Describe a potential safety hazard inherent in all capacitors
- Distribution Lines and Layouts
- Explain how electrical energy flows from a substation to the consumer
- List three categories of distribution lines and the classification of voltage carried by each line
- List and explain three types of distribution lines
- Protective Devices, Part 1
- Explain how circuit breakers operate to protect a distribution feeder from the effects of faults
- Explain how circuit breakers and fuses are used in a coordinated protective system to protect feeders and laterals from the effects of faults
- Explain how sectionalizing can be accomplished to protect customers from long outages
- Explain how reclosers operate to protect a distribution system from the effects of faults
- Protective Devices, Part 2
- Explain how reclosers and sectionalizers provide coordinated protection for a distribution system
- Explain how sectionalizing can be accomplished using reclosers and sectionalizers
- List and explain two devices that protect a distribution system from excessive current flow caused by voltage surges
