The U
Enp
setting must be adjusted to: U
Enp
= √3 · U
ng
= √3 · 6900 V = 11900 V
Example 2
The U
Enp
setting must be adjusted to: U
Enp
= √3 · U
ng
= √3 · 10000 V = 17300 V
• Measurement reading mode
Measures may be displayed according the following operating modes:
- With RELATIVE setting all measures are related to the nominal value,
- With PRIMARY setting all measures are related to the primary value.
