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.
Figure 3 Example SER Report
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
SYNCHROWAVE® Event Software or with Microsoft Excel.
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.

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.

Transformer Thermal Monitoring
Transformer thermal modeling, per IEEE C57.91-2011
or the IEC 60076-7:2018 Ed. 2, is a standard feature in
the SEL-2414. Specify the SEL-2414 to provide this
capability for monitoring and protection of a single
three-phase transformer, a three-phase transformer with
tertiary windings (three-winding mode with separate CT
ratios), or three independent single-phase units. Use the
thermal element to activate a control action or issue a
warning or alarm when your transformer overheats or is
in danger of excessive insulation aging or loss-of-life.
Use the thermal event report to capture current hourly
and daily data about your transformer. Operating
temperature calculations are based on load currents, type
of cooling system, and actual temperature inputs
(ambient and top-oil). Use as many as four thermal
sensor inputs: a single ambient temperature transducer
and one transducer for top-oil temperature from each of
three single-phase transformers. Temperature data are
obtained via an internal RTD/thermocouple card or from
an external SEL-2600A RTD Module. While the
SEL-2414 can receive temperature data at any rate, the
thermal element uses the temperature data once per
minute.
The thermal element operates in one of three modes,
depending upon the presence or lack of measured
temperature inputs: 1) measured ambient and top-oil
temperature inputs, 2) measured ambient temperature
only, and 3) no measured temperature inputs. If the
device receives measured ambient and top-oil
temperatures, the thermal element calculates hot-spot
temperature. When the device receives a measurement of
ambient temperature without top-oil temperature, the
thermal element calculates the top-oil temperature and
hot-spot temperature. In the absence of any measured
ambient or top-oil temperatures, the thermal element
uses a default ambient temperature setting that you select
and calculates the top-oil and hot-spot temperatures. The
device uses hot-spot temperature as a basis for
calculating the insulation aging acceleration factor
(FAA) and loss-of-life quantities. Use the thermal
element to indicate alarm conditions and/or activate
control actions when one or more of the following
exceed settable limits:
➤Top-oil temperature
➤Winding hot-spot temperature
➤Insulation aging acceleration factor (FAA)
➤Daily loss-of-life
➤Total loss-of-life
Generate a thermal monitor report that indicates the
present thermal status of the transformer. Historical
thermal event reports and profile data are stored in the
device in hourly format for the previous 24 hours and in
daily format for the previous 31 days.
The thermal model can be used even if a current card is
not installed. Current magnitude data can be received
through IEC 61850 Ed. 2 or other communications
protocols.
Through-Fault Event Monitor
A through fault is an overcurrent event external to the
differential protection zone. Though a through fault is
not an in-zone event, the currents required to feed this
external fault can cause great stress on the apparatus
inside the differential protection zone. Through-fault cur-
rents can cause transformer winding displacement lead-
ing to mechanical damage and increased transformer
thermal wear because of mechanical stress of insulation
components in the transformer. The SEL-2414 through-
fault event monitor gathers current level, duration, and
date/time for each through fault. The monitor also calcu-
lates a I2t and cumulatively stores these data per-phase.
The SEL-2414 through-fault report also provides percent
of total through-fault accumulated according to the IEEE
Guide for Liquid-Immersed Transformer Through-Fault-

Current Duration, C57.109-1993. Use through-fault
event data to schedule proactive transformer bank main-
tenance and help justify through-fault mitigation efforts.
Apply the accumulated I2t alarm capability of the device
to indicate excess through-fault current over time.
Load Tap Position and Control
Monitoring
The SEL-2414 supports load tap position and control
(LTPC) monitoring by using digital inputs in the
binary-coded decimal (BCD) or binary format. It can
monitor as many as 32 tap positions with one or three
neutral tap positions. Additionally, it monitors the raise
and lower controls to assert alarms for tap position
change failures or unexpected tap positions.
Implement individual tap position statistics monitoring
with the nonvolatile counters and voltage regulation by
using measured voltages, timers, and analog control
variables.

SEL-2414 logic improves integration in the following
ways.
Replaces Traditional Panel Control Switches
Eliminate traditional panel control switches with opera-
tor control pushbuttons or the 32 local bits, available
through the menu system. Program the four conveniently
sized operator pushbuttons to control fan banks and fan
lockout. Set, clear, or pulse local bits with the front-panel
pushbuttons and display. Program the local bits into your
control scheme with SELOGIC control equations. Use the
local bits to perform functions such as breaker trip/close.
Replaces Traditional Indicating Panel Lights
Replace traditional indicating panel lights with 32 pro-
grammable displays. Define custom messages (e.g., Fan
On, Fan Off) to report transformer or device conditions
on the front-panel display. Use advanced SELOGIC con-
trol equations to control which messages the device dis-
plays. Figure 8 shows an example.
Replaces Traditional Temperature Gauges
Replace traditional temperature gauges that show the
temperature, and the maximum and minimum tempera-
ture since last reset. The SEL-2414 Max/Min metering
records and time stamps the maximum and minimum
temperatures and transformer thermal model quantities.
Replaces Traditional Latching Relays
Replace as many as 32 traditional latching relays for
such functions as “remote control enable” with latch bits.
Program latch set and latch reset conditions with
SELOGIC control equations. Set or reset the nonvolatile
latch bits using optoisolated inputs, remote bits, local
bits, or any programmable logic condition. The latch bits
retain their state when the device loses power.
Eliminates External Timers
Eliminate external timers for custom protection or con-
trol schemes with 32 general purpose SELOGIC control
equation timers. Each timer has independent time-delay
pickup and dropout settings. Program each timer input
with any desired element (e.g., time qualify a current ele-
ment). Assign the timer output to control scheme logic.
Eliminates RTU-to-Device Wiring
Eliminate RTU-to-Device wiring with 32 remote bits.
Set, clear, or pulse remote bits using serial port com-
mands. Program the remote bits into your control scheme
with SELOGIC control equations. Use remote bits for
SCADA-type control operations such as trip and close.
