Electrical Fault-Finding & Troubleshooting

Unplanned downtime in an Industrial plant is costly and it is very important to keep the duration of such downtimes to a minimum.  Technicians with good troubleshooting skills are vital to ensure plant is up and running in the shortest period of time.

This course has been designed to provide participants with basic electrical troubleshooting techniques.  It covers an analytical method for troubleshooting commonly used electrical control systems. The correct safety procedures to be used in troubleshooting electrical equipment will be explained in detail. The participants will be given real-world scenarios as classroom exercise to reinforce theory.

Upon completion of this course, participants should have a basic understanding of electrical troubleshooting techniques used in industry.  Having this knowledge will help each technician develop confidence and professional enthusiasm, therefore, increasing their efficiency. The knowledge that technicians gain from this course will be further expanded by on-job training and practical experience they will receive throughout the duration of their career.

This very practical & hands-on workshop is deliberately limited to just six people and includes commonly used electrical equipment and components so that your faultfinding skills are built up by doing, not just by listening!!

Participant Profile:

This 2-day workshop, which is limited to 6 people, is targeted at technicians, crafts and new engineers working in the manufacturing industry who wish to apply their knowledge of electricity to the maintenance and repair of equipment. You don’t have to be a qualified electrician, but you would need a good understanding of electrical control circuits.

Learning Outcomes

On completion participants will:

1. Use single line diagrams and control system drawing in faultfinding.
2. Use of electrical testing tools in locating faults.
3. Be able to apply a logical approach to finding a fault in an electrical control circuit.
4. Apply faultfinding aids such as flow charts, system diagrams and circuit diagrams.
5. Appreciate the importance of documenting the maintenance history of a machine.

Course Content:

Theory

1. Understand the psychological barriers and the student’s own approach to problem solving.
2. Outline the basics of failure of components.
3. Systematic faultfinding using the six step procedure, Half split method and others.
4. Review use of specific troubleshooting frameworks such as tables, flowcharts and procedures.
5. Using documentation as an aid to faultfinding such as drawings, tagging and equipment identification, manuals, history etc.
6. Troubleshooting safety practices.

Practical

1. Read and wire-up schematic diagrams, which include relays, timers, contactors and overloads.
2. Analyse various faults using a disciplined approach such as six step method, etc. Build and fault find 0n electrical circuits such as ‘hold on’, ‘jog control’, ‘interlock & safety control’ and ‘remote start/stop’.
3. Use of electrical testing tools in locating faults.
4. Applying the theory to locating faults on a series of specially modified ‘real’ pump control panels that are used to control the level in a holding tank of a manufacturing process.
5. Real-world scenarios given as classroom exercise.

Testing

1. Mid course test to check progress in understanding different schematics and skills learned.
2. End of course written test based on work completed.
