SEL-351A Relay Instruction Manual Date Code 20080213
Standard Event Reports and SER
Example Standard 15-Cycle Event Report
Figure 12.3 Example Standard 15-Cycle Event Report 1/4-Cycle Resolution (Wye-Connected PTs)
Figure 12.5 and Figure 12.6 look in detail at 1 cycle of A-phase current
(channel IA) identified in Figure 12.3. Figure 12.5 shows how the event report
ac current column data relates to the actual sampled waveform and rms values.
Figure 12.6 shows how the event report current column data can be converted
to phasor rms values. Voltages are processed similarly.
