Learn Better Troubleshooting from Our Electrical Maintenance Training

Purpose of Seminar

Working with real world components and instruments found at their facility, attendees in this “hands-on” course will learn how to fix electrical problems plain and simple. It was created to bring students up to speed in their electrical troubleshooting skills as quickly and safely as possible and designed to cover the more commonly performed electrical troubleshooting tasks a maintenance technician faces in his job every day. For the novice or experienced electrician, this training course provides a no-nonsense, practical and real world systematic approach to electrical troubleshooting.

Students’ specific needs and concerns are also addressed during the class so that they can go back to their workplace and immediately apply what they’ve learned. This course can also be adopted as part of a company’s regular Qualified Electrical Worker program.

Course Overview

Attendees in this course will not be playing with trainers built for a classroom, but instead will be working with real world industrial components found in their facility, and they will be using real CAT III industrial meters to troubleshoot - just as they should in their facility.

The course will start with a quick review of safety before moving into a discussion on electrical symbols where students will learn to create their own electrical drawings to be used for troubleshooting. A review of meters and their uses ensues before a logical and systematic approach to troubleshooting is presented.

From here attendees will learn to troubleshoot industrial components from pushbuttons to relays and motor starters. They will physically wire basic electrical circuits using wiring diagrams as their guide, and then once they understand how they operate, they will troubleshoot faults inserted by the instructor. Discussions and hands-on exercises will also show students how to troubleshoot common electrical motors, including the determination of whether a problem is electrical or mechanical in nature. A phase-rotation meter, Megohmmeter and different types of multimeters and voltage testers will also be used during the class so that students become comfortable with and confident in their uses. Students will get the chance to see three-phase power in action and learn to measure its values. They’ll also test and troubleshoot single-phase power distribution systems.

A discussion of what electrical PPE should be worn for different tasks will take place as students try on different sizes and types of electrically rated rubber gloves so that they can see the importance of having a proper fit when working.

Power distribution problems will be discussed as well as testing for power quality issues and troubleshooting the different types of lighting circuits. A brief introduction to variable frequency drives and how to troubleshoot their most common problems will wrap up the course along with a final review of basic electrical preventive maintenance practices to keep your equipment from failing in the first place.

Who should take this course?

This seminar is designed for anyone who needs to sharpen their electrical troubleshooting skills in order to increase efficiencies and uptime at their industrial plant or building facility. If you work with electrical equipment and systems at industrial plants, commercial building, or private facilities, whether as general maintenance personnel, in cross-training programs, an electrician, or an engineer, you will find this course extremely useful. As long as you work with electricity and troubleshoot electrical problems, this course is for you.

The following personnel will benefit from our basic electrical training seminar:

  • All Building Maintenance Personnel
  • All Plant & Facility Maintenance Technicians
  • Electricians
  • Mechanics
  • HVAC Technicians
  • Boiler Operators
  • Machine Operators
  • Apprentices
  • Alarm Technicians
  • Non-Electrical Engineers
  • Building Engineers
  • Stationary Engineers
  • Low Voltage Specialists
  • Multi-craft & Cross Training Personnel

As well, it will benefit those who work in:

  • Manufacturing Plants
  • Commercial Buildings
  • Hospitals
  • Waste Water Facilities
  • Schools
  • Government Buildings
  • Research Facilities
  • Shopping Centers
  • Apartment Buildings

Training Outcomes

We have analyzed the job of the maintenance technician extensively to create a course that attendees are certain to find useful the minute they get back to work. So during this course attendees will perform basic electrical “hands on” maintenance tasks and when they return to work their employer can expect them to present a training certificate indicating he or she has successfully learned to do the following:

  1. Interpret the OSHA requirements for troubleshooting and working on energized circuits
  2. Safely and correctly verify a circuit is de-energized.
  3. Perform basic circuit checks for shorts, opens and ground faults
  4. Troubleshoot problems using ladder drawings and schematic diagrams.
  5. Perform continuity and resistance checks on relay coils and contacts, overloads, fuses, circuit breakers, switches and other control circuit components.
  6. Wire and troubleshoot basic electrical control circuits to develop a logical, systematic approach to troubleshooting
  7. Troubleshoot 3-phase circuits by taking and interpreting clamp-on ammeter readings
  8. Measure voltage on 3-phase Wye and Delta connected circuits and calculate percent phase imbalance as part of troubleshooting motors
  9. Test and troubleshoot single-phase power distribution systems for correct wiring.
  10. Use a Megohmmeter to perform the following insulation resistance tests used on motors and distribution systems: Spot Reading, Dielectric Absorption Ratio, and Polarization Index.
  11. Observe power quality problems and troubleshooting techniques for facility distribution systems, three-phase loads and commercial lighting.
  12. Measure VFD output characteristics and observe VFD operation.
  13. Apply troubleshooting skills to your facility one-line electrical drawings and electrical floor plans.
  14. Identify components of a successful electrical preventive maintenance program to minimize need for excessive troubleshooting.
