TRANSFORMER PROTECTION UNIT TPU TD410
OVERVIEW
The Transformer Protection Unit TPU TD410 is a protective
device with a full-integrated design. It is based on modern
digital technology and it complies with International Quality
Standards. With four central processing units, the TPU TD410
is certified as complying with the latest IEC Standards con-
cerning electromagnetic compatibility.
The TPU TD410 performs a wide range of protective functions.
Provided with many user-programmable options, it features
good accuracy in the setting of the current and voltage
thresholds, timings, and time-current functions. All protective
settings are independent. Two sets of parameters for each
protective function are available. All protective functions have
demanding security and speed constrains. As an example, the
differential function makes the amplitude matching of the
currents (according to the CT ratios of both sides), the proper
phase adjustments and eliminates the zero-sequence
component of the currents.
The graphic display in the frontal panel represents a synopticwith the panel complete state. In the frontal panel there are
also several functional keys that allow an easy command or
change of the panel working mode.
As a terminal unity, the TPU TD410 features accurate
measures of the differential and through-current for each
phase and for both sides of the transformer, as well as a set of
monitoring functions, including oscillography and data-
logging. These functions support the integration of the TPU
TD410 as a remote unity of the Supervisory Control and Data
Acquisition Systems of EFACEC-SE for Substations, while still
providing a link to PC.

PROTECTIVE RELAYING
Two-windings transformerdifferential protection (87T)
The transformers differential pro-
tection is a fast and selective re-
laying function aimed at protect-
ing transformers and at isolating
them from the Power System
when internal faults arise.
Adapting the sensed currents
A transformer differential protec-
tion start-up is constrained by the
value of the sensed differential
current (input current minus out-put current). It can also be con-
strained by the restraining cur-
rent (image of the current flowing
through the transformer). There-
fore, it is very important to use
the real values of those currents
which, as a rule, do not equal the
sensed currents.
The TPU TD410 assures a perfect
compensation for the sensed cur-
rents, in such a way that the dif-
ferential current image is zero forall the load and external fault
situations.
Therefore, the computation of the
differential and the restraining
currents includes a few compen-
sations, to avoid false differential
as well as false restraining cur-
rents resulting from unbalances
between HV and MV. Those com-
pensations depend on the trans-
former type and on the connected
CTs, and aim at:
• Eliminating any zero current cir-culating in the transformer
windings, to avoid the tripping of
the associated overcurrent vir-
tual relay against external
faults.
• Compensating the phase differ-ence resulting from the trans-
former type.
• Balancing the RMS values of thecurrents of different windings, to
compensate for different CT ra-
tios in the HV and MV sides of
the transformer.
Non restrained differentialrelaying
The non restrained differential
protection function for 2-windings
transformers operates with no
delay for differential currents
greater than a set threshold, usu-
ally a threshold high enough
(larger that the maximum inrush
current).
Restrained differential relaying
The operation of the differential
protection function for 2-windings
transformers is conditioned by
comparing the value of the differ-
ential current with that of the re-straining current, and also by the
2nd and the 5 th harmonics.
The operating characteristic ap-
plied to compare the differential
and the restraining currents is
made up by three continuous
segments, and it shows up as fol-
lows:
Idif
Irest
TRIP
LOCK α1
Imin
α2
Itth (to 2nd Slope)
The differential and the restrain-
ing currents are computed ac-
cording to the following expres-
sions:
IDIF = I HV – I MV
IREST = ½| I HV + I MV |
These currents have already been
compensated for any mismatch
depending on the particular
transformer and CTs. The follow-
ing directions are assumed:
IHV IMV
The first segment of the operating
characteristic is a minimum oper-
ating threshold (maximum sensi-
tivity).
The second segment accounts
mainly for the transformer tap
changing, as well as for any inac-
curacy in the CTs and the relay it-
self.
The last segment accounts for CT
saturation with high value cur-
rents arising with external faults.
2nd and 5th harmonic restraining
The harmonic restrain is applied
to avoid spurious tripping of the
differential protection, for high
magnetising currents. It is a tra-
ditional and well proved way to
recognise those currents.
The harmonic restrain works as
usually: it locks the protection op-
eration with the 2nd harmonic in
the differential current for inrush
currents, and it locks it with the
5th harmonic for overfluxing re-
sulting from either overvoltage or
underfrequency situations
The constrain is done by com-
paring the harmonic RMS values
to the RMS value of the funda-mental frequency component in
the differential currents. This
comparison is done for every
phase but is locking is performed
also for different phases.
Restricted Earth FaultProtection for the LV side(87N) - option
The TPU TD410 provides for the
LV side of the transformer an
instantaneous earth currentdifferential protection for solidly or
low impedance earthed systems.
The trip decision of this function
depends on the difference
between the sum of the three
phase currents and the neutral
point current.
The protection is unaffected by CT
saturation, inrush currents or
external faults.
Due to stabilise this function
against CT saturation, its
differential current sensitivity
depends on the through-current

Up to a certain limit, stability is
guaranteed with a linear
characteristic, with configurable
slope.
Tank OvercurrentProtection, for the HV side(50G) option
The TPU TD410 provides, as an
option for the HV side of the
transformer, the tank overcurrent
protection, which monitors the
current between earth and
transformer tank. This function
trips when this current is up to
the threshold value, which one is
normally set to a very sensitivevalue.
High Set Overcurrent with high-speed tripping (50, 50N)
The High Set Overcurrent function
is recommended as backup for
transformer faults and is provided
for the HV side of the transformer.
As a rule, the High Set
Overcurrent protection is targeted
for a selective coordination based
on the RMS current (cut off ). In
the TPU TD410, High Sets are
independent for protection from
phase faults and from phase to
ground faults. A selective timing
can also be set.
Low Set Overcurrent with timesets (51, 51N)
The Low Set Overcurrent function
is recommended as backup for
network faults. This protection
function is provided for the HVside of the transformer.
The Low Set Overcurrent
protection offers sensitivity and
step timings for selective
coordination (time-lag over-
current). The TPU TD410 provides
both the independent and the
inverse time options. Theseoptions comply with International
Standards, which is a guaranty
for compatibility with other
devices. The Standards are IEC
255-3 and IEEE 37.112 .
Setting the Low Set Overcurrent
relays is also independent for
phase-to-phase and for ground
faults.
For the IEC complying option, the
time-current functions follow the
general expression:
[ ]1)/( −>
=b I Icc
aT st op
NI a=0,14=A b=0,02VI a=13,5=A b=1EI a=80=A b=2
For the IEEE-complying option,
the time-current functions follow
the general expression:

The TD410 Unity supports the
timed resetting option in the time-
inverse operation of Low Set
Overcurrent.
Option for Timed Reset
Even for IEC time-inverse
functions, the TD410 supports the
option of timed resetting, thus
approximating the replication of
the conductors cooling down.
The resetting time follows the
expression:

It is worthy mentioning that the
accuracy of both the IEEE and the
IEC time-inverse curves is
guaranteed for the full range of
settings.
Also, the implementation of both
standards follows the dynamic
definition of IEEE 37.112,
providing a definite behaviour for
time-evolving faults.
This behaviour also supports a
dynamic co-ordination between
the relay and fuses as well as
traditional Reclosers downstream

Definite Time Overcurrent relaywith large setting ranges(Universal Overcurrent Relay)
The Low Set Overcurrent function
is recommended as backup for
network faults. This protection
function is provided for the HV
side of the transformer.
The TPU TD410 performs a
second Definite Time overcurrent
protection function, running inparallel and independence re-
garding the previous protective
functions.
The large setting ranges of this
protective function (Universal
Definite Time overcurrent relay)
supports a set of applications:
• For feeders with occasionallittle short-circuit capacity, in
which the operating times of
time-inverse overcurrentfunctions can feature big
delays, the Universal overcur-
rent protection provides a
limit for the operating time of
those low-set overcurrent
protective functions;

inverse option with timed

Option between a virtual imageof the zero sequence current
and the observation of the 4thcurrent input
The TPU TD410 is prepared to
observe the neutral current of the
HV winding of the transformer in
its 4th current input. However, the
TPU TD410 also performs by
software the computation of the
zero sequence current in that
winding, directly from the virtual
addition of the three phase cur-
rents observed at their inputs.
As a matter of fact, the neutral
current transformer available fre-
quently has a primary rated
current which is smaller than the
rated currents of the phase CT.
This fact may lead to saturation
whenever large fault currents
arise.
The virtual addition of the three
phase currents by the TPU TD410
supports the exploitation of the
extensive range of the phasecurrent transformers, while still
be-meting from the better accu-
racy reached by the 4th current
input for small currents.
The TPU TD410 makes it possible
to choose the residual current
source for each one of the three
ground fault relays, thus
supporting the combination of a
high sensitivity to high impedance
faults with the right observation of
strong ground fault currents.
Setting Sets
The TPU TD410 supports two
complete sets of settings, which
can be fully programmed by the
user.
Switching from a set to another
can be defined by a daily schedule
or by decisions from software
logic. This feature supports the
adaptation to different loadprofiles or network short-circuit
capacities, as time goes.
CONTROLING FUNCTIONS
Circuit breaker commands
The TPU TD410 supports thecommand of both HV and MV
circuit breakers, both for opening
and for closing, through func-
tional keys. These commands are
allowed either local or remotely,
and logic conditions can be
implemented, to provide full
automation.
Working modes
In the front-end 2 working modes
are established which may bechanged by pushing functional
keys. The actual working mode is
signaled by leds.
Manual/Automatic Mode
The manual mode inhibits all the
automatisms.
Local/Remote Mode
The local mode inhibits the com-
mands that may come from LAN.
Trip circuit monitoring
The TPU TD410 uses a contact
input aiming to constantly
supervise the trip circuit of the
circuit breaker when this is open.
In case there is any discontinuity
in the trip circuit when the circuit
breaker is closed (it needs to
monitor the state of the circuit

breaker), the input ceases to be
energized and an alarm is
generated.
Circuit breaker failure protec-tion
Following an order to trip the
circuit breaker, the circuit
breaker failure is verified.
If the protection does not reset
after a user-programmable time
(for example by circuit breaker
failure) a control is generated over
another equipment (for example
over the upstream circuit
breaker).
Circuit breaker close lock(86T)
The TPU TD410 blocks the HV
and MV circuit breakers close
command after a differential
protection trip or another
condition indicating a transformer
internal fault, such as the
Bucholz trip monitored by the
protection. This blocking condition
remains activated until the usersets the permission to put the
transformer in service again.
Interlocking and logical condi-tioning
The TPU TD410 contact inputs, as
well as a inner set of free logical
variables, which can be
associated to signals to be re-
ceived from the LAN and also to
the many protective functions,
can be logically combined andassociated to programmable
timers.
This flexibility in logical
conditioning can be applied to
define, for example, additional
interlocks to circuit breaker close
lock and trip commands.
MONITORING FUNCTIONS
Measurements
The TPU TD410 provides the
following metering values from its
steady-state condition:
• RMS values for the threephase and the ground
currents (4th input), for both
transformer windings.
• RMS values for the 1st, 2ndand 5th harmonics of the
differential currents.
These values are available either
on the TPU TD410 itself, or
remotely through a link to a local
area network and to the Supervi-
sory Control and Data Acquisition
systems of EFACEC.
The good accuracy achieved by
the performed measurements
usually make it possible to avoid
additional measurement
converters.
Other measurement informa-tion
The TD410 also computes and
records, with time-tags:
• The peak RMS values for thecurrents (1 second average)
• The addition of the I2 interruptedby each pole of the circuit
breaker, as well as the number
of its trips.
Oscillography
The TPU TD410 records and
stores the oscillography of the
phase and zero sequence
currents. The total length of each
oscillography is variable although
limited to 1 second, of which 0,1
seconds are for pre-fault values. A
variable number of oscillographies
up to 10 recorded seconds are
stored with a frequency of 1000
Hz.
The oscillographies can be
displayed on a PC, applying a
suitable software and retrieving
the information stored in the TPU
TD410 either through a front-end
connector, or remotely through
the Supervisory Control and Data
Acquisition System of EFACEC.
The good accuracy reached by the
performed measures usually
make it possible to avoid
additional measurement convert-
ers.
Sequence of Events Records
The TPU TD410 monitors all the
existing contact inputs andoutputs, as well as a set of inner
logic variables and any change on
the settings, performing an
accurate time-tagging of the
changes of state with a 1 millisec-
ond resolution and a programma-
ble debounce filtering time.
The record of the events stored by
the TPU TD410 can also be dis-
played on a PC, applying a
suitable software package and
retrieving the information either
local or remotely.
INTERFACES
Contact inputs
The base version of TPU TD410
has nine programmable contact
inputs that are isolated from one
another.
With an expansion board, nine
(expansion board type 1) or
sixteen (expansion board type 2)
extra programmable contactinputs can be added.

TPU TD410TPU TD410
This allows a maximum of 41
programmable contact inputs
with two extra expansion boards.
In the complementary inputs (forexample switches state, circuit
breaker open and close), if both
states are being monitored, the
invalidity state is reported if both
inputs have the same logical
value. However, only one input to
report the switches state can be
used, but, in this case, it is not
possible to report the invalidity
state.
Contact outputs
The base version of the TPU
TD410 has six independent
isolated contact outputs, of which
five are programmable.
The sixth output is double
(“change ove r”) and it is operated
by the inner “Watch-dog ” if the
relay fails.
With an expansion board type 1
six extra programmable contact
outputs are added.
This allows a maximum of 17
programmable contact inputs
with two extra expansion boards.
WinProt
To make the handling of the TPU
TD410 easier and to enhance its
features, the WinProt software on
a friendly and self-exploring
Windows environment is
available.
WinProt not only allows the exe-
cution of any operation on the
front-end, either locally or
remotely, but it also supports
more advanced functions, whose
highlights are:
à To retrieve, to change and to
save all the settings of the
TPU TD410. It is also possible
to print a brief report with
those settings.
à To retrieve the oscillographies
saved by the TPU TD410, and
to display them with
advanced zoom and format-
ting functions.
à To collect and to display the
sequence of events records.
Communication
The TPU TD410 provides a fibber
optic adapter on its back, for links
to a Local Are Network, using the
communication protocol LON
TALK or ETHERNET.
With the Supervisory Control and
Data Acquisition systems of
EFACEC, all WinProt features are
available remotely.
Man Machine Interface
In the frontal panel is supported a
graphic display where it is
presented a synoptic with the
state of the panel that is being
protected. By functional keys it ispossible to select and commandthe switches represented in the
synoptic (if they are
commandable, if not TD410 only
monitories its state).
The possible synoptics are chosen
from a set, by selecting the one
that better fits to the panel where
is associated the TD410.
By functional keys it is possible to
change the panel working mode
as well.
In an alarm window, in which the
alarms are there until they are
recognised it is possible to
recognise any incident in thatpanel.
The TD410 still supports a menu
mode where it is possible to
parameterise the protection
functions, to programme the
inputs and outputs, to command
the circuit breaker, to configure
the transformer measures relation
and to visualise informations.
The pursued philosophy regarding
the setting and command security is that everyone can access all the
information. However, no one can
change values without a
password.
The TPU TD410 has two security
levels. The first one only allows
the change of the setting of the
monitoring functions. The second
level allows the change of the
settings of the protection
functions.
After leaving an option level of themenu, the changes have to be
confirmed; otherwise, they will not
become effective. Not confirming
those changes in 5 minutes after
leaving the menu level will reset
all the parameters to the original
values.
