Figure 12.6 Example Sequential Events Recorder (SER) Event Report
The SER event report rows in Figure 12.6 are explained in Table 12.7,
numbered in correspondence to the # column. The circled, numbered
comments in Figure 12.3 also correspond to the # column numbers in
Figure 12.6. The SER event report in Figure 12.6 may contain records of
events that occurred before and after the standard event report in Figure 12.3.

SER
Row No.
Explanation
14
IN101 is asserted when the circuit breaker closes.
Related Setting: 52A = IN101
13
Time-overcurrent element 51G asserts.
12
Instantaneous-overcurrent element 50P1 asserts.
11
Phase-distance element M2P asserts.
10
Phase-distance element M1P asserts. This is an instantaneous trip condition.
Related setting: TR = M1P + Z1G + M2PT + Z2GT + 51GT + 51QT
9, 8 Outputs OUT101 and OUT102 assert.
Related setting: OUT101 = TRIP
OUT102 = TRIP
7, 6, 5, 4 Elements 50P1, M1P, 51G , and M2P deassert as the circuit breaker opens.
3
IN101 deasserts when the circuit breaker opens.
Related Setting: 52A = IN101
2, 1 Outputs OUT101 and OUT102 deassert.
