Start-up with medium voltage stator 71
Phase U current transformer polarity check:
• +1.5 V is connected to X1:1 of the NUIM-6x unit and
• -1.5 V is connected to X1:2 of the NUIM-6x unit.
06.01 STATOR IU measures positive values. The values depend on the used scaling
factors.
06.02 STATOR IY measures negative values, which are approximately 60% of the
STATOR IU.
Note: Values depend on the battery voltage and current transformer transformation ratio.
Note: When battery is removed, the signals behave in the opposite way.
