OMICRON Test Universe - Setting Relay Voltage Protection

[Joshua_Mc]

Good evening,

Does anybody have any experience with setting the voltage protection for REX640 relays using the Test Universe software? I cant seem to find anything about it else where.

Setting or testing? If testing a voltage element, you will probably want to test pick up & timing. You can do manually via Quick CMC or more automated via ramping/pulse ramping (pickup) and timing via the state sequencer. If you have a definite time element, you can set the delta T to something greater than the delay time and not have to mess with any settings in the relay. Generally speaking ramp from +/- (10-20%) of setting, meaning if the setting is 100V, ramp from 80-120 (Over Voltage) or 120-80 (Undervoltage).

There is not a dedicated module for voltage because the testing is quite straightforward. If you are used to a Doble or similar with 35 different macros, pick up=a ramp, time=a sequence.

Hope this helps.

Thanks for the info, it really helps a lot!

Also, I found that when I navigate through to the Application Configuration in the Test Object menu, I found that there is a section for the Voltage Protection with sections for Undervoltage/Overvoltage, would there be a way to link it to the testing schemes? Thanks in advance.

I see, you are using a Template supplied by Omicron. #1 thing is to read the pdf that comes with the template you downloaded. It will tell you what is covered and not covered in the template. Also how to import the settings from the Relay.

After that and if you want to link things you can. Ex in ramping you have a From and To (80V, 120V). If you right click on either field you can link to the settings listed in your pic above. You can also apply a little math such as From = 0.8*Overvoltagesettingname. Works the same in :To= 1.2* Overvoltagesettingname. Also works for the nominal value (expected result).

The right click is called Link to XRIO. Link to XRIO works in nearly all of the test modules. XRIO is the file format used in the Test Object part of the SW. The Test Object is the device you are testing, with the functions and settings you have entered or imported. You will notice that the values in the To/From fields change dynamically(once linked) if you change the value in the Test Object.

Ah okay, I think that's where my problem lies, whenever I try to use the LinkToXRIO the window doesn't show up, it just sits in the task bar. Would you know why this may be happening?

It looks to me from the screenshot you attached, you are right where you need to be. You are using an Omicron PTL template, correct?

 

[thermionic1]

I just used a SEL Relay PTL and was able to get here.

The screenshot I took is just from clicking on 'Test Object' in the Toolbar and navigating manually to the Application Configuration. When I go to use the LinktoXRIO nothing shows up.

Also, yes I'm using a OMICRON PTL template.

Yeah from your screenshot I can tell that I'm not getting the LinktoXRIO window, there may be an issue with my Test Universe.
