Sequential Events Recorder (SER) Report
Sequential Events Recorder (SER) Report
The SEL-2414 SER (Sequential Events Recorder) report gives you detailed infor-
mation on device element state changes over an extended period of time. The
SER captures and time tags state changes of Device Word bits and device condi-
tions. These conditions include power up, device enable and disable, settings
changes, and SER automatic removal and reinsertion.
The SER records up to 512 state changes of up to 96 Device Word bits listed in
the SER trigger equations. SER data are stored in nonvolatile memory, ensuring
that a loss of power to the SEL-2414 will not result in lost data.
Inputs
The SER guaranteed timestamp accuracy is ±1 microsecond for physical inputs.
The Transformer Monitor samples at 250 Hz or as a function of frequency; you
select frequency tracking by installing either an optional current card or an
optional voltage card (or both).
Chatter Filtering
The SER includes a filter function to prevent overfilling of the SER buffer with
chattering information. When enabled, the device automatically deletes these
oscillating items from SER recording.
