14.7 Capturing Waveform Data
The relay can record waveform data for the time just
before, during, and just after a fault. While this data
cannot be viewed on the front panel LCD, it can be
exported to a PC for analysis and viewing. The
sampling rate is 12 samples per power cycle. Data for
up to 3 faults is stored.
The storage of waveform data can be initiated in four
ways: (1) by the pickup of any active protection
function, (2) by the trip of any active protection
function, (3) by an external signal-contact input, or (4)
by a manual command using the front panel keypad.
The waveform recording-time period is divided into
three parts: the
pre
-
time
, the
middle
-
time
, and the
post
-
time
. The middle-time period begins when an
event initiates a fault log (a pickup, trip, contact-input,
or keypad-input). The middle-time ends with the
dropout of the protection function (for internally
initiated recordings), after a specified time period (for
recordings initiated by a signal-contact or a
keypad-input), or the external signal-input ends (an
option for recordings initiated by a signal-contact
input).
