Analyze Transformer Sequence-of-Events

Record sequence-of-events related to transformer events or operations with the Sequential Events Recorder (SER)
function. With this function, you can analyze assertions and deassertions of digital inputs and outputs; as many as 512
state changes to the millisecond for as many as 96 different digital points. The function also captures when the device
powers up and a settings change occurs.

Analyze Transformer Event
Waveforms
Record analog and digital waveforms at 32 samples/cycle for
as many as 64 power system cycles, approximately 1 s. Use
the event report to move the oscillographic data to your PC.
You can plot your event report data with the SEL-5601-2
®
WAV Event Software or with Microsoft Excel.
SYNCHRO E
Event reports contain ac currents, ac voltages, and digital
inputs and outputs. The report automatically adjusts
content to the I/O cards you use. Reports are stored in
nonvolatile memory to protect your data even if power is
lost. Event reports are optimized for recording power
disturbances and relating them to your process.
Set the report to capture either 15 or 64 power system
cycles of data around the trigger event. For a 60 Hz
system, the event report lengths are 0.25 s and 1.07 s. For
a 50 Hz system, the report lengths are 0.30 s and 1.28 s.

Trend Transformer Temperatures
and Other Analog Inputs
Record measured ambient, transformer top-oil, trans-
former hot-spot and other analog data (measured or cal-
culated) for trending with the Analog Signal Profile
function. This profile (trending) function can track as
many as 32 analog channels. The function records the
magnitude and time of acquisition of each analog chan-
nel. Use the profile report to move trend records to your
PC and quickly plot the data with Microsoft Excel or any
other spreadsheet application.
