For firmware version ≥ 2.0:
Decimal switching is not done via value of “CT ratio” setpoint, but in configuration window of LiteEdit
software via icon „Units/Formats“:
PT Ratio [/1]
Gen-set potential transformers ratio.
Step: 0.1 V / V
Range: 0.1 – 500,0 V / V
Vm PT Ratio [/1]
Mains potential transformers ratio.
Step: 0.1 V / V
Range: 0.1 – 500,0 V / V
NomVolts Ph-N [V]
Nominal generator voltage (phase to neutral)
Step: 1 V
Range: 80 – 20000 V
NOTE:
Phase sequence check is not possible to evaluate under voltage 50V what causes that if measured
voltage 50V is within the allowed range, controller will not allow to close the GCB, even if relevant LED
diode on front panel of IA-NT shining.
NomVolts Ph-Ph [V]
Nominal generator voltage (phase to phase)
Step: 1 V
Range: 138 – 35000 V
