Current and Voltage Columns

Table 49 summarizes the event summary report current and voltage columns.

Serialized Events

Recording (SER) Report

SER Triggering

The 825-P relay stores an entry in the SER report for a change of state of any

one of the elements listed in Table 112 on page 235 and Table 113 on page 238.
The relay saves up to 512 records in nonvolatile memory.

The relay adds the following message to the SER to indicate power up or settings
change conditions:

Relay newly powered up or settings changed

Each entry in the SER includes SER row number, date, time, element
name, and element state
