Measurement for U
Table 46: 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)
