Electrical Troubleshooting Training

Electrical troubleshooting training teaches maintenance personnel and technicians how to identify, analyze, and resolve electrical faults safely and efficiently. Participants learn systematic troubleshooting methods, test instrument use, and control circuit analysis used in industrial, commercial, and institutional facilities.

This 12-hour live online instructor-led course explains how to diagnose failures in motors, transformers, generators, breakers, cables, and control circuits, helping reduce costly unplanned downtime and improve system reliability.

Why Electrical Troubleshooting Training Matters

When electrical equipment fails, every minute of downtime adds cost through lost production, emergency labour, and damaged equipment. For some facilities, unplanned downtime can account for a significant share of annual revenue and an even larger share of profit. Technicians who can find the root cause quickly, rather than replacing parts by trial and error, get equipment back in service faster and stop the same failure from coming back.

This course teaches a structured approach to troubleshooting: define the problem, review symptoms and equipment history, read the drawings, and test logically and in sequence until the fault is isolated. Safe work practices, including lockout/tagout, PPE, and CSA Z462 requirements, are part of every step.

 

Test Equipment and Measurement Techniques

Participants review the instruments used for everyday electrical troubleshooting and learn how to use each one accurately and safely:

  • Use digital multimeters to measure voltage, current, and resistance, and to find open circuits and shorts
  • Measure AC current without breaking the circuit using clamp meters
  • Check insulation resistance with insulation testers on motors, transformers, cables, and switchgear
  • Locate hot spots and overheating connections with non-contact infrared thermometers
  • View electrical waveforms with oscilloscopes
  • Select the right meter category and understand voltmeter impedance for safe, reliable readings

 

Reading and Troubleshooting Control Circuits

Most electrical faults are found by tracing the circuit on paper first. Participants learn to read ladder diagrams, line and wire numbers, and standard symbols, and to follow AND, OR, and NOT logic through series, parallel, and complex circuits. The course covers the components found in industrial control systems, including disconnects, fuses, circuit breakers, relays, timers, overload relays, and manual and automatic switches.

 

Practical Troubleshooting Applications

Our electrical troubleshooting training course includes practical guidance on how to troubleshoot:

  • Motor starting, stopping, and overload problems
  • Transformer and power source problems
  • Circuit breaker, fuse, and disconnect failures
  • Relay, timer, and latching circuit faults
  • Limit, pressure, temperature, flow, proximity, and other automatic switch failures
  • Pumping, heating and cooling, and conveyor control circuits
  • Forward/reversing, two-speed, jogging, and reduced voltage starting circuits
  • Ground-fault and overload protection problems

 

Preventive Maintenance and Recordkeeping

Good troubleshooting depends on good records. Industry experience shows that regular maintenance can prevent a large share of electrical failures, and accurate as-found and as-left drawings, equipment change logs, and trend data make each future fault easier to diagnose. The course shows how to use troubleshooting results to strengthen your facility's preventive maintenance program.
