A Lineworker’s Worst Nightmare
Every year in the United States there are multiple lineworker accidents and deaths caused from a contact incident. Every person in the industry should always have this in the back of their minds about the what if’s. Hear firsthand from one of these people on how their accident occurred and how it has affected their lives and the lives of those around them since that day.

Safety is Number One, Brent Jeffries, Bierer Meters
Bierer Meters has been in business for over 30 years. They have been providing lineworkers dependable tools such as phasing meters, voltage detectors, personal grounds, and more. This session will give participants the proper knowledge and best practices on how to use these meters to get accurate readings when needed.

TWO CLASS OPTIONS: Multi-Session Class or Advanced Class


Note: The Multi-Session Class is intended for lineworkers of all experience levels. Registrants will rotate through the following sessions. (The Advanced Class does not rotate.)

Session #1 - Troubleshooting and System Maintenance
Participants will have the opportunity to practice several different troubleshooting techniques including testing, grounding and proper rubber cover up. A primary goal will be to focus on becoming proficient at system maintenance while adhering to all safe work practices and methods. Different scenarios will be presented that participants will be instructed to repair/fix. Scenarios may include broken jumpers, delta-bank backfeed, tracking insulators, cracked/broken cutouts, tree on line, etc.

Everyone understands that working on lines or equipment as deenergized requires testing and grounding. This class offers instruction on the proper methods of grounding lines and equipment. Students will be taught the proper way to utilize phasing sticks in the process of grounding, as well as phasing in cables.

Session #2 - Capacitor Bank and Maintenance
 Placing power factor correction and passive harmonic filtering equipment on an electrical system needs to be properly designed and maintained. This session will cover everything you need to know about capacitor banks--from knowing what a capacitor is to the result of placing one in service. The dangers associated with capacitor banks, proper fusing, proper testing, and safety precautions associated with working on capacitor banks will also be covered.

Session 3 - Construction of a Double Circuit Line
In this session, participants will be installing new poles within an existing pole line to increase height for an additional circuit. Individuals will receive the proper instructions on how to safely install the new poles and transfer over the existing lines. Several techniques for moving the existing line and creating a safe work environment will be utilized.

Session 4 - Staking Overhead Lines
Before the poles and wires go up, the lines must first be designed and staked. This session will cover the process involved when building new overhead lines. Having a straight line of poles is about more than aesthetics; the straighter the poles, the stronger the line will be making it more resistant to strong winds and ice.


GIS Mapping
Switching from paper maps to electronic maps can be a large undertaking. Get started learning about the fascinating and useful world of geographic information systems (GIS). In this course of the specialization GIS, Mapping, and Spatial Analysis, you'll learn about what a GIS is, how to get started with the software yourself, how things we find in the real world can be represented on a map, and how we record locations using coordinates. This course will give you a strong foundation in mapping and GIS that will give you the understanding you need to work with GIS.
