Understanding Microprocessor Relay Logic – Microprocessor Relay Testing Plans

We have uploaded our fourth YouTube video, Understanding Microprocessor Relay Logic – Microprocessor Relay Testing Plans. (http://youtu.be/ijdSKozctNo) This video discusses how to turn the microprocessor relay testing logic into microprocessor relay testing test plans.

This video series is a re-creation of the first paper I ever presented from the NETA conference in 2001 that was the foundation of The Relay Testing Handbook series.

The video describes some of the most useful tips for engineers, including:

• Use the relay’s native software to create the relay settings
• Supply a print-out of the FINAL settings as a separate, version controlled drawings
• Create drawings of the output logic that anyone can understand as a version controlled drawing.

The video also describes some tip for relay testers, including:

• Add the nameplate data, including ratings, to your test sheet
• Perform a pick up and timing test of each element used
• Always test the in-service outputs
• Add a copy of the FINAL settings to your test sheet
• Write down the password!!

We’ve learned a lot about the YouTube format while creating this series and, unfortunately, it turns out converting PowerPoint to video is a little dry. Future video series will be much better.

We hope you found this video informative and hope you’ll stick with us as we get better with each series.
