Overview

This course will introduce and provide non-technical people with the basics of the overhead distribution system and all the general components that make up the system. Issues that are involved in the design, construction, operation, reliability, protection and maintenance of overhead distribution, as well as safety awareness will be discussed.  It will allow people who are not distribution engineers to know enough to oversee projects or simply have a better understanding of the system.


Agenda

MONDAY, OCTOBER 7, 2019 8:00 – 5:00 p.m

8:00 – 8:30  a.m. :: Registration and Networking Breakfast


Distribution – What is it?

  • The power system from generator to customer
  • Major types of distribution systems
    • Overhead
    • Underground
    • Network
  • Typical distribution system configurations
    • Feeders
    • Branch lines
    • Descending hierarchy

How Distribution Systems Work – Electrical Part I

  • Voltages, amps, resistance
  • Single phase and three-phase
  • Power and impedance

How Distribution Systems Work – Electrical Part II

  • Power quality
    • Voltage drop, flicker, harmonics
    • Power Factor
  • Voltage regulation

Design Considerations – What is That?

  • Major materials
    • Poles, crossarms, conductors, equipment
  • Smaller materials
    • Primary and secondary materials
    • Nuts, bolts, washers, and more
  • Pole top assemblies
    • Horizontal and vertical configurations
    • Alternate construction configurations
  • Guying
    • Guy attachments, guy wire, anchors
  • Transformers
    • What they are – how they work
    • Three-phase configurations
    • Photo quiz
  • Special electrical equipment
    • Regulators, auto transformers, capacitors, metering

Design Considerations – Why is it Built That Way?

  • Codes and regulations
    • National Electrical Safety Code (NESC)
    • Other regulatory agencies
  • Mechanical and electrical
    • Equipment sizing
    • Conductor sag, tension, clearance
  • Operations
    • Utility and industry standards
    • Line crew considerations
  • Storm hardening
    • Definitions
    • Stronger or more resilient?

Design Considerations – Why Are Those Lines Where They Are?

  • System analysis
    • Load flow and power quality
    • Line and equipment loading
  • System planning
    • Projecting future new loads
    • Modeling the future system               
  • Other considerations

TUESDAY, OCTOBER 8, 2019 8:00 – 12:00 p.m


Operating Considerations – What Does it Take to Keep the Lights On?

  • System protection
    • What line faults are
    • Devices used to handle fault conditions
    • System protection schemes
  • Special situations
    • Distributed generation
    • Disruptive loads
  • Public perceptions and pressures

Improving Reliability – What are Utilities Doing?

  • Switching and protective devices
  • Automated switching and reconfigurations
  • Automated outage reporting
  • Storm hardening

Modernizing the System – Can Old Dogs Learn New Tricks?

  • Energy sector R&D
  • Utility programs

Safety – Saving the Most Important Topic for Last

  • Electrical considerations
    • Public safety
    • Employee safety
    • Stray voltage
