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 CHARA CTERISTICS
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.

2.1.4 Other features of main outputs
- Zero crossing control. Main AC outputs are generated and stopped as the output waveform crosses 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.
- Output adjustment: from less than 5% to 100% of the output.
- Output measurement. The used output (current, V AC, V DC) is selected by a dedicated push­button; the selected socket is confirmed by a light.
2.2 AUXILIARY AC VOLTAGE
- The auxiliary AC voltage output, V AC aux, is isolated from the main AC current and voltage.
- Output ranges: 65 – 130 - 260 V. NOTE: at 15 Hz, the output ranges are: 25, 50, 100 V.
- Range selection: software driven, by the multi-function knob and LCD display.
- Auxiliary voltage power: 30 VA, continuous duty, at full range; 40 VA for 1 minute. At 15 Hz, the power is: 8.5 VA at 25 V; 13 VA at 50 V; 16 VA at 100 V. For lower voltages the limiting current is the following.

- Output stability: the adjusted voltage drops of 5% maximum from zero load to full load.
- Output adjustment: continuous. For normal tests the voltage is continuously supplied, and the output voltage is adjusted by the dedicated knob.
- Output connection: safety banana sockets.
- ON-OFF switch to enable the output. A light confirms when the output is available.

- 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 pre­fault 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)

- Possibility to define the duration TPF of pre-fault generation, after test start, prior to generating fault values. This feature is necessary to test synchronization relays: the main output voltage can be applied prior to frequency switching. TPF range: from 0 to 999.99 s.
- Possibility to change the frequency of the auxiliary AC voltage output. Frequency generation characteristics: . Frequency range: 15.000 Hz to 550.000 Hz. . Frequency adjustment: 1 mHz, via control knob. . Frequency generation error: 100 ppM. . It is possible to switch from the nominal frequency to the fault one. The nominal frequency is also selectable, independently from the fault. . Switching from nominal frequency to fault frequency is performed without altering the output voltage (figure 3).
