It's just a matter of time. Troubleshooting will be required at your workplace regarding an electrical problem. This problem could be as simple as a lighting circuit, or it could be as complex as a variable frequency drive (VFD) control circuit. When this time comes, it's going to require a certain skill (troubleshooting) to ascertain the problem, diagnose the circuit/component, and provide a solution to return the suspect circuit or component back to normal operation as soon as reasonably possible. What is a skill? The dictionary states that a skill is (1) A developed talent or ability; (2) An ability that has been acquired by training; (3) Ability to produce solutions in some problem domain. The ability to troubleshoot encompasses all three definitions. Definition ‘1’ relates to the troubleshooting skill that has already been developed. Definition ‘2’ relates to one aspect in the development of a troubleshooting skill. Definition ‘3’ relates that once the skill has been developed, one can produce solutions. This is where HPC Technical Services comes in. This course will provide the minimum skills required in the development of troubleshooting effectively. Additionally, to hone your skill of troubleshooting, a myriad of circuits will be used that represent the ones that you will most likely come in contact with.
Also, this course will describe the importance of having an electrical preventive maintenance program. Topics discussed include: Basic Skills for Electrical Troubleshooting. Followed by discussion on Troubleshooting Control Circuits, Motors, Power Quality Problems, Lighting Problems, PLC’s, and Variable Frequency Drives. Finally, the topics turn to Preventive Maintenance issues.
