reports

c2 drafted · lead Islanding detected

Stand-alone grid or very large grid frequency change detected.

has_event_class

c3 drafted · lead Fault (device stops or needs intervention)

review note: support check: partial - Passage labeled 'Grid fault' with feed-in stopped, but fault classification is implied rather than stated.

has_production_effect

c4 drafted · lead Trip (production stops)

detected_by

c5 drafted · lead Grid frequency measurement

review note: support check: partial - Passages only say to check the grid connection for frequency fluctuations; frequency measurement as the detection method is implied, not stated.

mitigated_by

c6 drafted · lead Utility company consultation

If a power outage or grid work is suspected.
