Electrical Distribution Safety

December 5, 2023 | Online :: Central Time

Electric distribution lines are the thoroughfare for power from the local substation to the distribution transformer which modifies it to usable power for household appliances and commercial/industrial equipment. The power is lethal in that it measures in the thousands of volts and yet it is less than 100 feet from residences and business.

This course provides key insight as to how these power lines can coexist with the general public with relatively few safety-related incidents. Course discussion will cover:

  • Electricity basics and power concepts
  • Best system design practices and industry standards (National Electric Safety Code)
  • System maintenance and repair
  • System fault isolation and storm restoration
  • Protection devices and systems
  • Cost/benefit of design options, especially overhead versus underground lines

Special discounts apply for groups of five or more so register your whole team today!

Learning Outcomes

  • Review the electric power system
  • Review hazards and lethal limit of exposure to an electric current
  • Identify and demonstrate hazards that may be encountered in overhead and underground distribution systems
  • Discuss causes of System Fault and Fault Isolation
  • Identify and review use of personal protective equipment necessary for working near energized lines and equipment
  • Evaluate preparations necessary before performing work at distribution work sites
  • Employ the appropriate tools and equipment to use in performing overhead and underground distribution systems

Transmission Line and High-Voltage Substation Electrical Safety

December 6, 2023 | Online

This course is designed to cover the basic safety considerations relating to performing maintenance work on high voltage transmission systems and substations, including personal safety, electrical safety, and work site safety.

This intensive one-day course will cover safety aspects related to satisfying OSHA Requirements 29 CFR 1910.269 and 1926.950 which covers the operation and maintenance of electric power generation, control, transmission, substations, and equipment. Attendees will be taught:

  • Potential hazards in overhead, underground, substations and switchyard maintenance
  • Processes involved in working on energized lines:
    • Safely isolating, insulating and de-energizing a transmission line to make the line safe to work on and restoring that line to service
  • Principles of equipotential grounding and how it safeguards line workers
  • Proper communication, proper clothing, and protective equipment
  • Best practices in preparing to work on a variety of transmission and substation worksites

Register now to gain a better understanding of the hazards of transmission line maintenance and the precautions necessary to mitigate the risk of injury or death.

Learning Outcomes

  • Describe the individual’s role in safety and proper communication
  • Demonstrate an understanding of hazards that may be encountered in overhead, underground, and substation and switchyard maintenance work and know how to avoid them
  • Identify and use protective equipment necessary for working near energized lines and equipment
  • Evaluate preparations necessary before performing work on a variety of transmission and components
  • Employ the appropriate tools and equipment to use in performing overhead, underground, substation, and switchyard maintenance
  • Describe the basic steps in making T&D equipment electrically safe to work on, including line de-energization and equipotential grounding
  • Revies fundamental substation awareness information
