Data record `tests.phase-rotation-and-phasing.ieee1547-1.synchronization-check`

Verified 2026-10-24 Confidence: High

Commissioning test CT2 in clause 8.2.3.2 of IEEE 1547.1-2020 checks and records the phase rotation on both sides of the interconnection and, where a synchronizing relay is used, confirms that closure of the breaker is blocked outside the design limits; the criteria refer to the frequency, voltage and phase-angle difference limits of IEEE 1547-2018 Table 5 for synchronous DER and to the rapid voltage change limits at paralleling.

Provenance. Where this record comes from and where it is used: the cited source, the record itself and the entry that cites it.

Provenance: the chain from source to entry.
