SEL-351P Manual Técnico
• Instantaneous overcurrent element pickups (67P1, 67G1, 67N1)
Any time one of these elements picks up or drops out, the relay time-tags the change in the SER.
The other two SER factory settings (SER2 and SER3) trigger rows in the SER event report for
the following conditions:
• Changes in breaker status (52A) and reclose operations
• When control is powered down due to low battery (TOSLP)
• Other battery and battery-charger status-related Relay Word Elements
The control adds a message to the SER to indicate power up or settings change (to active setting
group) conditions:
Relay newly powered up or settings changed
Each entry in the SER includes SER row number, date, time, element name, and the new element
state.
Making SER Trigger Settings
You can enter up to 24 element names in each of the SER settings via the SET R command. See
Table 9.3 for references to valid recloser control element (Relay Word bit) names. See the SET
R command in Table 9.1 and corresponding Settings Sheet 20 of 23 at the end of Section 9:
Setting the SEL-351P Recloser Control. Use either spaces or commas to delimit the elements.
For example, if you enter setting SER1 as:
SER1 = 51P1T, 51G1T 51P2T,,51G2T , 50P1, , 50P2
The relay displays the setting as:
SER1 = 51P1T 51G1T 51P2T 51G2T 50P1 50P2
The control can monitor up to 72 elements in the SER (24 in each of SER1, SER2, and SER3).
Retrieving SER Reports
The control saves the latest 512 rows of the SER in nonvolatile memory. Row 1 is the most
recently triggered row, and row 512 is the oldest. View the SER report by date or SER row
number as outlined in the examples below.

SER If you enter only “SER<ENTER>”, all available rows are displayed
(from row 1 to row number 512). The rows display with the oldest row
at the beginning (top) of the report and the newest row (row 1) at the end
(bottom) of the report. Chronological progression through the report is
down the page and in descending row number.
SER 17 If you enter the SER command followed by a single number (17 in this
example), the first 17 rows are displayed, if they exist. They display
