Data record `tests.relay-27-undervoltage-test.ieee2800.no-mandatory-settings`

Verified 2026-10-24 Confidence: Medium

IEEE 2800-2022 states no undervoltage trip setting for a transmission-connected inverter-based resource plant, as clause 7.2.1 makes explicit; clause 9.3 requires any voltage protection that is applied to permit the voltage ride-through of clause 7.2.2, so the setting against which an undervoltage element is tested is a project value coordinated with the transmission system owner rather than a value from the standard.
