The test current configured is automatically set according to the result in Auto Mode: 110% of the measured I
ds
.
When entering a value manually, ensure that it is higher than the trip level of the High-speed DC Circuit Breaker.
The type of injection can be selected (active selection is marked red):
1. 90% to 110% (default option)
2. 60% to 110%
High-speed DC Circuit Breakers with an inductive shunt (di/dt sensitive) may trip during the rising slope of the
injection. For this reason, the 60% to 110% option is available to avoid a trip during the rising slope.
To start the test, press the ‘Start’ button.
