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


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:

trearme [s]= 1)/( 2−> I I A

It is worthy mentioning that the

accuracy of both the IEEE and the

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

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;

• As the main Low Setovercurrent protection

element, with Definite Time,

element becoming available to

replicate the thermal behavior

of the feeder conductors,particularly in the extreme

inverse option with timed

resetting.

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.


8/14


4DV002007 8 / 14

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.
