Figure 31: Connection Schematic for Ungrounded Single-Phase Split-Phase Network for Power
Measurement for U
Table 38: Legend for Figure "Connection Schematic for Ungrounded Single-Phase Split-Phase
Network for Power Measurement for U
No. Explanation
1
Generator:
Generator or transformer in single-phase split-phase connection, without
neutral conductor grounding
2
Current transformer (CT3) for current measurement in the neutral
conductor (optional)
3
Loads with impedances (Zx):
- Load connection: in split-phase connection
- Load type: all variants
4
Connection terminal N:
Reference potential for all voltage inputs and differential current inputs
5
Connection terminal L2:
Connection to the N connection (optional, to avoid erroneous measured
values for the unused phase)
