ABB REF615 Relay Fault Report Checking Process

[@风景这边独好-g4k]

Hello, I'm very sorry to disturb you on the weekend. I have a question that has been bothering me: after changing the settings of the protection relay, do I still need to conduct a test? For example, the overcurrent protection has been changed from 5A to 6A. Do you still need to test the relay protection? Thank you

NO you don't need to test it again. But for your peace of mind you can !

@@terrabuddy4321 I'd like to find a way to check and confirm that the parameters I've changed are correct

In REF 615 relay go to: Settings ↩️ Then again settings (there will be another settings group - don't go there) Then Edit group 1 - click enter Then Current Protection Under Current Protection several different protection schemes will be present - check which ones are ON (by clicking the right arrow key). Which ever schemes are ON - you will find it's details below it - check if the changes that u made are correct - then go back and save. I am assuming you have changed the parameters and now you want to check if the changes you made are saved or not. If you want to check whether the new settings are suitable for your system or not without undergoing testing - then verify those settings by calculation.
