What you’ll learn

  • Importance of fault recording

  • Different types of faults

  • Standalone & built in fault recorders

  • how to review fault record by software

Dear All,

I have created this course keeping in mind to share my field knowledge about fault recording with you.

We have all studied the symmetrical components & types of faults during university and college time. Wondering how real fault data would look like and how to read fault records.

In this training I will share with you all that is required to review faults records, you will be able to download fault recorder software as well as comtrade files to review records your self.

The importance of keeping fault logs; Fault logs are used to record incidents and errors on a system, these faults can then be used in the future if the problem occurs again so the technician can resolve the problem quickly without having to troubleshoot it again.
