SH ORT FO REWORD
Dear T 1000 PLUS user,
I often wondered why the user’s manual is not very much used,
even if it includes valuable information. As me too I am a user of
such manuals, the answer I have given myself is that valuable
information are concealed somewhere in the thick thing, and I do
not have time to waste to find it. So, either the manual is actually
of help, or I ignore it.
This is why I decided to split the T 1000 PLUS manual in three:
specification, with all performance details; application manual,
with instructions about how to use it one its operation is
understood; introductory guide, with the device description and
basic information. The idea is that you may read once the
introductory guide or the specification, while you need to follow
application examples more than once; so, why not to split the
manual in three?
Have a good work with T 1000 PLUS!

* For distance relays three T 1000 PLUS are necessary.
** Differential starter circuit
In addition to the above, T 1000 PLUS can test:
. Converters: V; I; φ°; p.f.; W; VAr; f., both 0 to 5 and 4 to 20
mA.
. Energy meters, single phase or three phase.

DOC. MIE92093 Rev. 1.34 Page 7 of 108
The instrument contains three separate generators:
. Main generator, which generates either AC current, AC voltage;
DC voltage;
. Auxiliary a.c voltage generator, that generates an independent,
phase shifting a.c voltage;
. Auxiliary DC voltage generator, that generates the DC voltage
that feeds the relay under test.
All outputs are adjustable and metered at the meantime on the
large, graphic LCD display. With the multi-purpose knob and the
LCD display it is possible to enter the MENU mode that allows
setting many functions, which make T 1000 PLUS a very powerful
testing device, with manual and semi-automatic testing
capabilities, and with the possibility to transfer test results to a
PC via the USB interface. These results can be recorded,
displayed and analyzed by the powerful TDMS software, which
operates with all WINDOWS versions, and allows creating a data
base of all tests in the plant.
The basic T 1000 PLUS function is to generate current and
voltages and to stop generation as the relay trips. Test results are
kept in memory, and can be transferred to a PC at a later time,
along with settings.
The ease of operation has been the first goal of T 1000 PLUS: this
is why the LCD is graphic, and so large. With it, the dialogue in
MENU mode is made easy. Besides, all T 1000 PLUS outputs are
continuously measured, and output values are displayed, with no
extra effort to the operator. Also the show waveform feature can
be of help: any doubt about strange measurements, distortion
and so on can be solved.
This is also why we have added the reduced power feature.
Modern relays have a very low burden. As current output is a low
impedance voltage generator, adjusting low currents and/or
current on low burdens is quite difficult because one has to
operate at the very beginning of the adjustment knob. In this
situation it is possible to connect resistors in series; however, one
must be careful not to exceed the maximum current rating, and
the wiring is more complicated. The solution to this problem is
just to reduce the available power: this is easily performed via

DOC. MIE92093 Rev. 1.34 Page 8 of 108
the multi-function knob. With less power, the maximum voltage is
reduced by a factor of 4.4; the adjustment span on the knob is
increased accordingly.
Additional features are:
. Two meters, current and voltage, with independent inputs, allow
measuring T 1000 PLUS outputs or any other source;
. Two auxiliary contacts, that allow simulating the circuit breaker;
. A set of resistors allows easing output adjustment.
The instrument is housed in a transportable aluminum box, that
is provided with removable cover and handles for ease of
transportation.

1.1 CONNECTION TO THE RELAY AND POWER-ON
At first, be sure that the main control knob (6) is turned (rotated)
to the zero position (complete counter-clockwise). The reason is
that the current generator is actually a high current voltage
generator. If the output is connected to the load (typically low
impedance), as soon as the test is started, a very high current
can circulate in the circuit.
Next connect the mains supply cable to the instrument and then
to the supply. THE SUPPLY VOLTAGE MUST BE THE SAME AS
INDICATED ON THE PLATE.
Power-on T 1000 PLUS: a diagnostic sequence controls:
. Key microprocessor board components;
. Auxiliary supply voltages.
If something is wrong, the operator is alerted by a message.
At the end of it, default selections are active; T 1000 PLUS is in
the OFF state.
Perform the first selections, according to the type of relay to be
tested:
. Main output socket, acting on the selector push-button (57).
. Auxiliary AC voltage: range; type of generation; value. NOTE: to
perform the range selection, the output must be ON, and the
value reduced to the minimum.
. Auxiliary DC voltage: range; value. NOTE: to perform the range
selection, the output must be ON, and the value reduced to the
minimum.
. Start and Stop timer inputs.
Connect the relay to be tested to the output sockets that have
the indication light (LED) on.
The following is the list of protections that avoid damaging T 1000
PLUS in case of errors.

DOC. MIE92093 Rev. 1.34 Page 10 of 108
. Fuse on the mains supply.
. Thermal NTC sensor on the main and auxiliary transformers. In
case of over-temperature, an alarm message is displayed.
. Thermal sensors on the SCR that controls current injection, and
of the internal temperature. In case of over-temperature, an
alarm message is displayed.
1.2 TEST CONTROL
The T 1000 PLUS front panel is explained in next paragraph.
T 1000 PLUS generation is controlled by the two keys < (55) and
> (56).
Settings and menu selections are controlled by the multi-function
knob with switch (22): see next paragraph for menu selections
description. At power-on T 1000 PLUS generation is OFF, as
confirmed by LED (50). The ON selection serves for finding relay
thresholds; selections ON+TIME and OFF+TIME serve to measure
relay timing.
The following flow diagram summarises all available test control
selections.
The performance of T 1000 PLUS in Normal Test mode is the
following.
. OFF: main outputs are not generated; Vac aux is generated,
and it can be either the pre-fault value or the fault value,

DOC. MIE92093 Rev. 1.34 Page 11 of 108
according to selections; Vdc aux is generated. In this condition,
any trip of Stop input is ignored.
. ON: timer starts; main outputs are generated; Vac aux has the
fault value; Vdc aux does not change. In this situation any trip at
Stop input is detected; it is possible to verify and memorize the
relay threshold, both trip and reset. As the relay trips, the TRIP
LED (43) turns on for 5 seconds; during 5 seconds, parameters at
trip are displayed; then, the standard measurement is restored.
Test results can be saved according to Save selections.
. From OFF to ON + TIME: main outputs are generated and the
timer starts according to selections; as Stop trips or resets, T
1000 PLUS returns to OFF, the TRIP LED (43) turns on and
parameters at trip are displayed until ON or ON+TIME are
selected. Test results can be saved according to Save selections.
. From ON to OFF + TIME: main outputs are removed the timer
starts according to selections; as STOP is sensed, T 1000 PLUS
returns OFF, the TRIP LED (43) turns on and parameters at trip
are displayed until ON or ON+TIME are selected. Test results can
be saved according to Save selections.
Other test mode selections:
. Relay or Breaker selection. Sometimes the test set is used to
monitor the CB contact instead of the relay contact. In this
situation the delay is longer than the relay delay, as the CB delay
adds to the relay delay.
If the test is time limited, it may occur that, while the relay trips
within the programmed maximum generation time, the CB
contact switches after this time. In such a situation, the time
measurement would be Not tripped.
To solve this issue, there is the selection Relay or Breaker. If
Relay is selected, then the time measurement is stopped as the
maximum fault generation time expires; if Breaker is selected,
the timer keeps on measuring for 100 ms after the decay of the
fault maximum time. The diagram explains the situation.

DOC. MIE92093 Rev. 1.34 Page 12 of 108
. Trip + pulse time: the timer measures the delay and the
duration of the trip impulse.
. Reclose test. It is possible to select via menu the test of a
reclosing scheme. Two selections are available, according to the
type of recloser under test.
In the first operating mode, T1000 PLUS is connected as follows:
Trip command to the STOP input; Reclose command to the START
input. As Reclose is detected, the test set automatically applies
current after the programmable reclaim time delay TD. The test
set measures and stores the relay trip delay, and the delay
between trip leading or falling edge and RECLOSE trailing edge
(see figure 4). The test set waits the close command up to 9999
s.
The sequence is repeated the programmed N times; after this, a
last fault is issued, and the test set verifies that there is no Close
command. On the last fault, the test set waits up to 10 times the
last Close delay before stopping the test.
During this operation, the auxiliary contact A1 can be used to
simulate the CB position: this is mandatory for the test of some
Recloser. The test starts with the CB position Closed; at the end
of the last test, it comes back to Closed.

The second operating mode refers to pole mounted CB’s. In this
mode, there is only one signal coming from the device under test:
the position of the CB. In this mode, the operation is the
following.
In this test mode the test set is edge triggered; the CB position is
connected to the STOP input, and, from the Closed –Open
position, the test set derives the Start and Stop commands, to
perform the test as above.
Other Fault injection selections:
. Maintained (default):
.. ON mode: fault outputs are generated until OFF is selected.
.. ON+TIME or OFF+TIME: as the STOP input is sensed, T 1000
PLUS returns OFF.
. Momentary: in ON mode, main outputs are generated until the

. Timed: in all modes (ON; ON+TIME; OFF+TIME), fault outputs
are generated for the programmed maximum time; after this, T
1000 PLUS returns OFF. Any trip after this time is not sensed.
. External. This mode allows for the synchronization of more T
1000 PLUS: they start generating upon reception of the START
input, that is selected in External mode.
. OFF delay: fault parameters can be maintained for the specified
time after relay trips: this allows simulating the circuit breaker
delay.
Test power selection: it allows reducing the available power; this
increases the adjustment sensitivity for low current tests on low
burden relays.
Save selections:
. No automatic saving.
. Automatic test data saving as relay trips. A pop-up window
confirms the saving and tells the test number.
. Test data can be saved after confirmation. After relay trip,
pressing the multi-function knob the operator can save the test
result.
. Manual test data saving. This selection can be used any time: it
serves if the trip is confirmed by a light and not by a contact.
Auxiliary contacts delays: the switch of the auxiliary contacts can
be timed with respect to test start.
1.3 CURRENT GENERATION
If the following current limits and time duration of main current
outputs are trespassed, the generation is interrupted, and the
operator is warned by an alarm message.

This generator serves for the test of current, power, directional,
distance relays, where current or current and voltage are
necessary. The procedure is the following.
. At first, be sure that the main control knob (6) is turned
(rotated) to the zero position (complete counter-clockwise).
. Power-on T 1000 PLUS.

DOC. MIE92093 Rev. 1.34 Page 17 of 108
. Select by the push-button (57) the measurement on the desired
output sockets (13), according to the maximum current to be
generated: the LED turns on; the AC voltage value is displayed.
. Connect the relay to be tested to sockets (13). Consider that for
tests of 40 A up it is necessary to connect the relay by a wire
having at least a cross section of 10 sq. mm; for lower currents, a
cross section of 2.5 sq. mm can be used.
. Press ON and adjust the output current to the desired value with
knob (6).
. After you have started the test, if the burden is a short circuit
made of a short cable, you measure at zero knob position a
current that usually is less than 3% of the range. This value does
not influence at all the measurement of the current you are
generating: it is not an error of the measurement
instrument. If the current is a problem, select the 60 VA power,
and/or connect resistors in series.
. There are two more possible problems: the desired current
cannot be reached; the adjustment is difficult because the current
is reached too easily.
.. If it is impossible to reach the desired value, this is because the
burden is too high. Very often the problem comes from
connection wires; so, to perform the test it is necessary either to
shorten them, or to increase the cross section (or both).
.. If the adjustment is reached within 1/5th of the knob rotation,
then it is possible to increase the ease of adjustment by reducing
the test power as follows.
TEST CONTROL > TEST POWER (Power) ESC
.. It is also possible to increase the ease of adjustment by
connecting a resistor of the set in series to the relay. Resistors
are rated 50 W; so, compute the resistance value as follows:
(RESISTANCE) = 50 / (TEST CURRENT)^2
Maximum test current values are resumed here below.

Note that the test starts and stops as the current passes the zero.

1.4 AC VOLTAGE GENERATION FROM MAIN OUTPUT
If the current of 3.5 A is exceeded on main AC voltage output,
the generation is interrupted, and the operator is warned by an
alarm message.
This generator serves for the test of synchronism relays, where
two voltages are necessary. The procedure is the following.
. At first, be sure that the main control knob (6) is turned
(rotated) to the zero position (complete counter-clockwise).
. Power-on T 1000 PLUS.
. Select by the push-button (57) the measurement on output
sockets (60): the LED turns on; the AC voltage value is displayed.
. There are two ranges available: 250 V (full power); 57 V
(reduced power). The default at power-on is full power; if 57 V
are enough, for a better adjustment, reduce the voltage as
follows.
TEST CONTROL > TEST POWER (Power) ESC
. Adjust the output voltage to the desired value with knob (6).
. Connect the relay to be tested to sockets (60). Check that the
adjusted voltage does not drop as you connect the relay; else,
this would mean that T 1000 PLUS is overloaded (or that you are
connecting to a live wire). In this situation, remove the cause of
error and connect again.
1.5 DC VOLTAGE GENERATION FROM MAIN OUTPUT
If the current of 3.5 A is exceeded on main DC voltage output,
the generation is interrupted, and the operator is warned by an
alarm message.
This generator serves for the test of timers and all devices that
are driven by a DC voltage. The auxiliary DC voltage generator
cannot be used to this purpose as it is continuously generated: no
time measurement can be performed. To this purpose, act as
follows.
. At first, be sure that the main control knob (6) is turned
(rotated) to the zero position (complete counter-clockwise).
. Power-on T 1000 PLUS.

DOC. MIE92093 Rev. 1.34 Page 19 of 108
. Select by the push-button (57) the measurement on output
sockets (61): the LED turns on; the DC voltage value is
displayed.
. There are two ranges available: 300 V at 300 W continuous (full
power); 68 V at 60 W continuous (reduced power). The default
at power-on is full power; if necessary, reduce the power as
follows.
TEST CONTROL > TEST POWER (Power) ESC
. Adjust the output voltage to the desired value with knob (6).
. Connect the relay to be tested to sockets (61). Check that the
adjusted voltage does not drop as you connect the relay; else,
this would mean that T 1000 PLUS is overloaded (or that you are
connecting to a live wire). In this situation, remove the cause of
error and connect again.
1.6 AC VOLTAGE GENERATION FROM THE AUXILIARY OUTPUT
The auxiliary AC voltage is used to test relays that need voltage
and current at the meantime. In this situation, the voltage is
continuously generated; usually, it is adjusted to the nominal
value, and it is not changed during all tests. It is possible to
phase shift the current with respect to voltage; selections are the
following.
. Power-on T 1000 PLUS: the output voltage is zero. Press the
push-button (70) to enable or disable the output; when enabled,
light (62) is ON, and the AC voltage value is displayed on the
screen.
. There are three ranges available from 45 Hz up: 65; 130 or 260
V AC; the power is 30 VA continuous; 40 VA peak for 1 minute.
For increased power and accuracy, it is better to select the range
that is closest to the value to be generated. The default at
power-on is 65 V; if necessary, select the desired range.
. At lower frequencies, the maximum output and power
decrease. The table summarizes the situation at 15 Hz and 33.33
Hz.

. The operating mode is pre-selected as Fault: do not change it.
Do not change also the pre-selected frequency, as Locked to
mains. Last, set the desired current phase angle; however, to
perform this, T 1000 PLUS must be ON, and some current must
circulate. Selections are performed as follows.
AUX VAC/VDC > Aux Vac control > Range > (Range) RET
Phase > Reference:
current > (Phase) ESC
NOTE: to perform the range selection, the output must be ON
(press push-button (70)), and the value reduced to the minimum,
else the test set alerts to reduce it.
This performed, adjust the voltage to the desired value with knob
(20). Eventually, connect the relay to be tested to sockets (62).
Check that the adjusted voltage does not change or the overload
message pops up as you connect the relay; else, this would mean
that T 1000 PLUS is overloaded (or that you are connecting to a
live wire). In this situation, remove the cause of error and
connect again (reset the alarm if it popped up).
Execute the test, modifying the phase angle as necessary.
This output is also used for the test of voltage relays, frequency
relays, synchronism relays; frequency rate of change relays. In
these instances, it is necessary to use the Pre-fault + Fault
selection. This feature allows adjusting two different values: the
