No. Explanation
1 Generator:
Generator or transformer in ∆ connection, with grounding of a line
conductor
2 Loads with impedances (Zx):
- Load connection: in ∆ connection
- Load type: symmetrical or asymmetrical
3 Loads with impedances (Zx):
- Load connection: in Y connection
- Load type: symmetrical or asymmetrical
Note that an asymmetrical load leads to a star point shift in the load.
4 Connection terminal N:
Reference potential for all voltage inputs and differential current inputs
≤ 400 V (Example with L2 as Grounded Line Conductor)
RMS
≤ 400 V (Example with L2 as Grounded Line Conductor)"
