peace be with you all Can you give me an idea, how to test SIEMENS 7sj622 directional o.c and directional e.f fault relay by using omicron .freja or any Numerical testing instrument? regardes mohammad elhaje
I am attempting to test the Negative Sequence Overcurrent on a 351 and 351S with an Omicron test set and my test plans just don’t seem to be working very well. I have managed to get a one shot to work but not an automated plan any suggestions? gcerniglia
This post is pretty old. I suggest you check this post to get a better idea of my thoughts on test-sets. https://relaytraining.com/what-is-the-best-protective-relay-test-set/ I understand Chris has a Manta MTS-5000, do you like it! Does anyone else has info on the Manta? What about other test equipment? Thanks for any info you
This has been bothering myself and some of my employees for a while. GE Quads are extended on the reach axis by the k factor of the relay, settings engineers that we have been working for are basically matching the reach settings of other manufacturers or the calculated reach settings
