Functional Overview
SV
The SEL-487E subscribes to data streams that are pub-
lished by merging units, such as the SEL-421-7 SV Pub-
lisher or SEL-401 Protection, Automation, and Control
Merging Unit. The SEL-421-7 SV Publisher provides
additional backup protection while the SEL-401 can pro-
vide basic backup protection with phase-overcurrent and
breaker-failure protection in the absence of communica-
tion. The data may be synchronized using Precision Time
Protocol (PTP).
