ANSI definition:
Ratio of the largest difference between the phases and the average of all 3 phases.
If one of these parameters exceeds or falls below its default settings, the trip unit is tripped after the adjusted delay via the c.
The parameters can be adjusted via:
- the test socket with the BDA
- the PROFIBUS-DP
- the MODBUS
- the graphical display (ETU776).
