Im3/ErFlCurCTp [ A ]
Mains current phase 3 or Earth Fault protection Current Transformer ratio – primary side.
Mains CT ratio for single phase Import / Export power and PF measuring. Single phase power value is
internally multiplied by three.
Step: 1 A
Range: 1 – 10000 A
Hint:
Im3 controller terminals have to be connected to mains L3 phase for Import/Export measuring!!!
Balanced mains power is expected.
Im3/ErFlCurCTs [ /5A / /1A ]
Mains current phase 3 or Earth Fault protection Current Transformer ratio – secondary side selection /5A or
/1A. Available in IG-xxC and IS-NT versions. In standard IG-EE/NT units only 5 A range available.
Hint:
Do not switch to 1A range unless you have IG-NTC/EEC or IS-NT hardware.
VT ratio [ /1 ]
Gen-set Voltage Transformers ratio.
Step: 0,1 V / V
Range: 0,1 – 500,0 V / V
Vg InpRangeSel [ 277 V / 120 V ]
Gen-set voltage sensing inputs range selection. Available in IG-xxC and IS-NT versions. In standard IG-
EE/NT units only 277 V range available.
Hint:
The range 277 V is suitable for both European (230 V) and American (277 V) measurement.
The range 120 V is intended for high-voltage applications where voltage transformers with output range 100
V are used, or for alternative American (120 V) measurement.
Do not switch to 120V range unless you have IG-NTC/EEC or IS-NT hardware.
Vm VT ratio [ /1 ]
Mains Voltage Transformers ratio.
Step: 0,1 V / V
Range: 0,1 – 500,0 V / V
Hint:
Set VT ratio to 1,0 if no Voltage Transformers are used.
Vm InpRangeSel [ 277 V / 120 V ]
Mains voltage sensing inputs range selection. Available in IG-xxC and IS-NT versions. In standard IG-EE/NT
units only 277 V range available – the setpoint setting is not important.
Hint:
The range 277 V is suitable for both European (230 V) and American (277 V) measurement.
The range 120 V is intended for high-voltage applications where voltage transformers with output range 100
V are used, or for alternative American (120 V) measurement.
Do not switch to 120V range unless you have IG-NTC/EEC or IS-NT hardware.
GenNomV [ V – kV* ] (FV)
Nominal generator voltage (phase to neutral).
Step: 1 V / 0,01 kV*
Range: 80 V – 300,0 kV*
Force value possibility: Yes
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
