Electrical Troubleshooting & Preventive Maintenance On-Site Training

This on-site training class is also available as Public Schedule Seminar.

Teaching students common-sense electrical troubleshooting techniques so they can keep their facilities and equipment up and running is the primary goal of this seminar. Learning how to protect themselves from serious injury while doing it is a vitally important bonus.

Course Description/Agenda

Teaching students common-sense electrical troubleshooting techniques so they can keep their facilities and equipment up and running is the primary goal of this seminar. Learning how to protect themselves from serious injury while doing it is a vitally important bonus.

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. And more than just a "hands-on" training course, we have analyzed the job of the maintenance technician and provide training on some of the more commonly performed electrical troubleshooting tasks. You can and should expect results from this seminar!

Attendees in this course will not be playing with trainers built for a classroom but, instead, they'll be working with real world industrial components found in their facility. They will be using CAT III industrial meters to troubleshoot - just as they should in their facility. They will troubleshoot industrial components from pushbuttons to relays and motor starters. They will wire basic electrical circuits using wiring diagrams and then, once they understand how they operate, they will troubleshoot faults inserted by the instructor. They will use a phase-rotation meter, Megohmmeter and different types of multimeters and voltage testers. They will see three-phase power in action and learn to measure its values. They will learn what electrical PPE they should wear and will even have the opportunity to try on Flame Resistant (FR) clothing. They will try on different sizes and types of electrically rated rubber gloves and learn what they should be using in the field.

Granted, we can't substitute years of experience in a day or two of training, but we can show you how to safely and correctly troubleshoot electrical components and circuits based on your career level. At American Trainco we provide "Real World Training?for Real World Needs."

Who should take this course?

This seminar is a must for anyone who works with electrical equipment and systems at industrial plants, utilities or commercial and private building facilities. General maintenance personnel, workers in cross-training programs, electricians and engineers will find this course extremely useful. Attendees come from a wide variety of industries, skill-levels, company sizes, and job titles, so if you're not sure you'll fit in or will benefit from the class, don't worry - you will - as long as you work with electricity!

  1. Interpret the OSHA requirements for troubleshooting and working on energized circuits
  2. Determine the Personal Protective Equipment (PPE) requirements for electrical troubleshooting.
  3. Safely and correctly verify a circuit is de-energized.
  4. Perform basic circuit checks for shorts, opens and ground faults using a multimeter.
  5. Read and interpret simple ladder and schematic diagrams.
  6. Perform continuity and resistance checks on relay coils and contacts, overloads, fuses, circuit breakers, switches and other control circuit components.
  7. Wire and troubleshoot basic electrical control circuits to develop a logical, systematic approach to troubleshooting.
  8. Take clamp-on ammeter readings on 3-phase circuits and interpret readings.
  9. Measure voltage on 3-phase Wye and Delta connected circuits and calculate percent phase imbalance as part of troubleshooting motors.
  10. Test single-phase power distribution systems for correct wiring.
  11. Use a Megohmmeter to perform the following insulation resistance tests used on motors and distribution systems: Spot Reading, Dielectric Absorption Ratio, Polarization Index.
  12. Observe power quality problems and troubleshooting techniques for facility distribution systems, three-phase loads and commercial lighting.
  13. Read and interpret basic PLC ladder diagrams.
  14. Measure VFD output characteristics and observe VFD operation.
