The instrument contains three separate generators:
. Main generator: it generates either AC current, AC voltage; DC voltage;
. Auxiliary AC voltage generator: it generates an independent, phase adjustable AC voltage;
. Auxiliary DC voltage generator: it 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, which allows
setting many functions, which make T1000 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
RS232 interface. These results can be recorded, displayed and analysed by the powerful TDMS
software, which operates with all WINDOWS versions, starting from WINDOWS 98 included.
The basic T1000 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 T1000 PLUS: this is why the LCD is graphic, and so
large. With it, the dialogue in MENU mode is made easy. Besides, all T1000 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 the multi-function knob.
With less power, the maximum voltage is reduced by a factor of five; the adjustment span on the
knob is increased accordingly.

2 CHARACTERISTICS
2.1 MAIN GENERATOR
The main generator has three outputs: currents, voltage AC, voltage DC. The following
specification applies to the separate usage of these outputs. It is possible to use them at the
meantime, provided that the total maximum load is not exceeded.
The main generator is made of a variable transformer followed by a transformer. The variable
transformer does not reach the zero position; so, when you are adjusting the output current on a low
burden, the minimum current can be up to 5% of the range. If this is a problem, select the 60 VA
power: the current is reduced to one fifth.
For all main output generators there is no specification related to the output distortion. This is
because the output waveform follows the mains supply waveform, with its distortion. If it is desired
to avoid distortions, the option FT100 solves the problem.
2.1.1 Main AC current
- Type of generator: voltage, high current output: the current depends upon the burden.
-On all outputs is provided the capability of generating the selected current at maximum power or
at reduced power. Reduced power selection eases the current adjustment for modern relays, where
the load is negligible. Current ranges; available power; duty cycle: see the table below.

zero. This implies that in mode ON+TIME the output drops to zero from 0 to one cycle after STOP
is detected.
- Overload alarm message. When the nominal current range is trespassed a message is displayed.
- Thermal protection: by NTC. Trespassing of the maximum temperature is signalled by a message.

- Possibility to phase shift the auxiliary AC voltage output with respect to: the main current and the
main AC voltage. The phase angle reference is the auxiliary voltage. Phase shifter characteristics:
. Phase angle adjustment: via the multi-function knob.
. Phase angle range: from 0° to 360°.
. Adjustment resolution: 1° (degree).
- Possibility to define the pre-fault voltage: in this mode, the control knob allows to adjust the pre-
fault value, while the dedicated knob adjusts the fault value. Voltage output selection is automatic:
pre-fault voltage with test stopped; fault voltage with test started. The switch from a value to the
other one is performed without falling to zero. The main current or voltage is generated at the zero
crossing; the fault one is generated at the meantime of main voltage or current (figure 1). The
selection of the reference is performed automatically, following the selection of main output
measurement. If the main DC voltage is selected the reference is taken on the main AC voltage.
This feature allows testing voltage relays (27-59) or synchronizing relays (25).

- Possibility to phase shift the pre-fault voltage, at an angle independent from the fault voltage. This
parameter serves during the test of distance relays, when phase to phase faults are simulated: as test
starts, the fault voltage changes amplitude and phase with respect to the pre-fault value (figure 2)

2.4 TIMER
The electronic digital timer has a fully automatic start and stop, both for make and break of the
input, which can be either a clean contact or a contact under voltage. All selections are menu-driven
via the multi-function knob.
- Characteristics of Start and Stop inputs:
.. Inputs do not have any common point, and are opto-coupled from the instrument at 1.35 kV AC;
.. Inputs connection: two banana sockets per input;
.. Inputs may be independently selected as Normal Open or Normal Close;
.. It is also possible to select timer start or stop as the current is injected and timer start/stop on input
transition;
.. Selections are displayed on the front panel by 10 dedicated lights;
.. Type of input: either clean or under voltage; selection via the multi-function knob. Maximum
input: 250V AC or 275 V DC;
.. For both inputs, when the input is closed or with voltage an LED turns on;
.. When the relay intervenes, the TRIP light turns on;
.. Wrong selection protection. If a voltage is applied when the clean input is selected, input circuits
are not damaged.
- Input thresholds: when the contact has voltage applied, two thresholds can be selected. The low
setting applies to nominal voltages of 24 and 48 V; the high setting to 110 V up.

- Display reset: automatic, at test start.
- Counting mode: this mode is foreseen for the test of energy meters. Maximum input frequency: 10
kHz; voltage threshold can be set as for tripping. It is possible to select this mode via menu, and to
set the number of impulses; the test set counts all impulses applied to START input after ON and
during all generation, and measures the time elapsed during the count.
2.5 TEST CONTROL
- Manual start control:
. OFF: main outputs are not generated; V AC aux is generated, and it can be either the pre-fault
value or the fault value, according to selections; V DC aux is generated.
. ON: main outputs are generated; Vac aux has the fault value. In this situation it is possible to
verify and memorize the relay threshold, both trip and reset.
. From OFF to ON + time: main outputs are generated and the timer starts according to selections;
as STOP is sensed, main outputs are removed and the elapsed time displayed and test result can be
memorized.
. From ON to OFF + time: main outputs are removed the timer starts according to selections; as
STOP is sensed, the elapsed time is displayed and test result can be memorized.
. Test control: by two push-buttons.
- Other test control selections:
. Momentary: in ON mode, main outputs are generated until the push-button is pressed;
. Timed: main outputs are generated for the programmed maximum time;
. External. This mode allows for the synchronization of more T1000 PLUS.
- Reclose test. It is possible to select via menu the test of a reclosing scheme. Two selections are
available, according to the type of the recloser under test.
In the first operating mode, T1000 PLUS is connected as follows: Trip command to the STOP
input; Close command to the START input. As Close is detected, the test set automatically applies
current with 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 CLOSE trailing edge (see figure 4).
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.

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 fault generation commands, to perform the
test as above.
The following specification applies to both operating modes.
- Range of TD: from 0 to 999.9 s. Maximum number of Reclose commands: 49; maximum test
duration for all Reclose commands: 9999 s.
- Circuit breaker delay simulation: possibility to set the delay from relay trip to generation off.
Delay range: 0 to 999 ms or 0 to 999 cycles.
- Save selections:
. No automatic saving.
. Test data can be saved after confirmation. After relay trip, pressing the multi-function knob it is
possible to save the test result.
2.6 AUXILIARY CONTACTS
- Two auxiliary make and break contacts.
- Each contact can be separately programmed to close (open) at test start, or after a programmable
delay. Contacts switch off when the STOP input is sensed.

- Delay range with respect to test start: from 0 to 999.99 s.
- Maximum time error between current and make/break contact: 2 ms.
- Contacts range: 5 A; 250 V AC; 120 V DC
2.7 OUTPUTS MEASUREMENT
2.7.1 Current and voltage
- The following three outputs are displayed at the meantime on the LCD display:
. The selected main output: AC current, or AC voltage, or DC voltage;
. Auxiliary AC voltage output;
. Auxiliary DC voltage output.
- Type of measurement: true rms for AC outputs; average for DC outputs.
- Readings, resolution and accuracy: see table. Note that the available ranges can be greater than the
maximum value of the socket to which the load is connected: this means that higher values can be
measured without saturation. For example, on the 100 A output the measuring range is up to 999 A.
Actually, the test set will not generate more than 250 A, as the test is stopped by the software, that
indicates overload, and on the display currents more than 250 A will not be shown.

2.9 DISPLAY
The graphical display has the following main features:
-pixels: 240x64
-backlight color: white
-LCD type: FSTN
-View area: 135x40
During the standard operation the display shows the measurements of: main AC current (or main
AC voltage or main DC voltage, according to selection); auxiliary AC voltage; auxiliary DC
voltage; elapsed time. To the left is the area for the access to the menu selection.
2.10 MENU SELECTIONS
The following is the list of features that are menu selected. The menu is operated by means of the
control knob marked MENU that incorporates a switch. The menu is entered pressing the knob and
selecting the item moving the knob. Once the item has been found and programmed, pressing the
arrow the menu moves back of one step, so that other programming can be performed; else,
selecting ESC the menu returns to the main window.
During this operation the display shows output measurements, in reduced format. After
confirmation, menu messages disappear, and measurements are displayed in the standard format.
Any setting can be saved to and recalled from the memory. Up to 10 settings can be stored and
recalled; setting no. 0 is the default one, and pops up at power-on. Settings are permanently stored
in the memory; new settings can be written to the same address after confirmation. For normal
mode operation it is possible to recall the standard setting that cannot be modified.
During the test, test results can be stored in the memory (up to 500 results may be stored). At the
end of test, settings and test results can be transmitted to a PC provided with TDMS. The software
allows saving test results, examining them and so on. The specification of TDMS is given in a
separate document. When the PC is connected, settings can also be created and transferred into
T1000 PLUS using TDMS. The flux diagram of menu selections can be found in Appendix 1.
