Electrical Equipment Troubleshooting Matrix Investigation, Analysis & Diagnosis

Troubleshooting is a method of finding the cause of a problem and correcting it. The ultimate goal of troubleshooting is to get the equipment back into operation. This is a very important job because the entire production operation may depend on the troubleshooter's ability to solve the problem quickly and economically, thus returning the equipment to service. Although the actual steps the troubleshooter uses to achieve the ultimate goal may vary, there are a few general guidelines that should be followed.
 

There are often cases where a familiar piece of equipment or system breaks down. In those cases, an abbreviated troubleshooting process can be used to find the fault, get the system up and running. It is important to note that the steps are simply combined to be specific to the problem at hand.

• Verify that a problem actually exists
• Isolate the cause of the problem
• Correct the cause of the problem
• Verify that the problem has been corrected
• Follow up to prevent future problems
• Understand the various types of fault currents
• Determine the causes of overcurrent and short circuit   current
• Explain the differences between symmetrical & unsymmetrical faults
• Understanding the technology of most electrical equipment and control systems.
• Understanding the philosophy of different maintenance methodologies and ways of practically implementing these methods for different equipment at different voltage levels.
