Parameters
Signal Name
Average Voltage [V]: Average voltage of U
UL1L2, UL2L3, UL3L1: Line voltages
Overvoltage Trip/Warn: True if one line voltage is above the adjusted overvoltage trip/warn
level.
Undervoltage Trip/Warn: True if one line voltage is below the adjusted undervoltage trip/warn
level.
Phase Loss: One or more phases are lost (e.g. fuse blown)
U Imb.: The voltage imbalance value
U Imb. Trip/Warn: True if the voltage imbalance is above the adjusted trip/warn level.
Wrong Phase Sequence: Output is set if a wrong phase sequence was detected.
THD L1, L2, L3: Total harmonic distortion on the phase.
THD Warn: Output is set if the total harmonic distortion is above the configured warn level in a
phase.
