Why are the ABB Other trip times higher than expected?
If the trip times for your ABB Other are higher than expected, the threshold or curve might be set too high. Another possibility is that the curve type is set to "t=k/I2". Finally, the neutral selection could be incorrect. To resolve this, correct the threshold and curve, select the curve type "t=k", and ensure the neutral adjustment is correct.
Why are the ABB Other trip times lower than expected?
If the trip times for your ABB Other are lower than expected, it could be due to a threshold or curve that is set too low, or an incorrect neutral selection. To fix this, correct the threshold and curve settings, and ensure the neutral adjustment is correct.
How to troubleshoot ABB Other when the trip test cannot be run?
If the trip test for your ABB Other cannot be run, it could be due to several reasons. First, check if the busbar current is greater than 0, as it should be in normal operation (FN). Second, verify the TC connection. Lastly, ensure the PR030/B unit is properly connected.
What to do if the expected trip does not happen with ABB Emax X1 Other?
If the expected trip does not occur with your ABB Other, the protection function might be turned off. To resolve this, enable the protection function (FN).
What causes rapid trip with I3=Off in ABB Emax X1?
A rapid trip with I3=Off in your ABB Other is likely caused by an instantaneous trip (Iinst tripped). This suggests a short-circuit with high current (FN).
