46 & 47 Part 03

Описание: If you saw my some of my old posts showing a slew of calculations and wanted to learn how to perform 46 & 47 element testing on a relay, then you are in luck. This is video 3 of 12 in a series coined "Negative Sequence Made Easier". This is a typical element for motor and generator protection.

I want people to stop being intimidated and also stop improperly testing this element. You should know what to expect BEFORE you test the relay. This series will go over how to find the right information, how to test pickup, how to test timing (mostly), and how to properly assess these tests. Again, you should know all of this BEFORE you start the test. I am covering over 10 different relays which is a ton of information. I cannot cover everything, but with this under control anything else should be possible.

I hope this helps, and I look forward to seeing your comments!
