This 57-minute DVD describes how distribution systems are laid out, and their component parts. It shows how to recognize transformers, voltage regulators, and capacitors, and explains in general terms, how each works. It introduces the process of sectionalizing, and demonstrates how protective devices protect the system from damage, and its customers from outages.
|Training Sessions |
- Introduction to Distribution Systems – 7 minutes
Lists the basic components used in a distribution system. Explains the basic differences between primary and secondary distribution systems.
- Transformers – 9 minutes
Defines the term transformer, and explains in general terms how a transformer works. Using a simplified diagram, identifies basic elements common to most transformers. Shows how to recognize pole top, pad-mounted, and subsurface transformers.
- Voltage Regulators and Capacitors – 12 minutes
Defines voltage regulator. Identifies the electrical and physical elements that make up a typical voltage regulator. Explains in general terms how a voltage regulator works. Defines a capacitor and explains in general terms how a capacitor works. Describes a potential safety hazard inherent in all capacitors.
- Distribution Lines and Layouts – 9 minutes
Explains how electrical energy flows from the substation to the consumer. Lists three categories of distribution lines and the range of voltage carried by each line. Shows three types of distribution layouts
