No. Explanation
1 Generator:
Generator or transformer in Y connection, without grounding or with defined
ground impedance (ZE)
2 Generator:
Generator or transformer in ∆ connection, without grounding
3 Loads with impedances (Zx):
- Load connection: in ∆ connection
- Load type: symmetrical or asymmetrical
4 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.
5 Connection terminal N:
Reference potential for all voltage inputs and differential current inputs
