The protection relay does not include any batteries as backup power
when the auxiliary power goes down. However, the relay
configuration and settings, events, disturbance recordings and any
critical data stay in the relay's memory because those are saved to a
nonvolatile memory. Also, the relay's real-time clock is kept running
via a 48-hour capacitor backup.
