The Transformer Turns Ratio Analyzer Series 2 (TTRA-S2) software is a Windows-based PC
software application for use with Vanguard’s Series 2 line of three-phase transformer turnsratio testers (ATRT-03 S2, ATRT-03A S2, ATRT-03B S2, and Tri-Phase). This software allows users
to perform the following tasks:
• Test winding turns-ratios of transformers, voltage regulators, and load-tap changers
directly from a PC.
• Create test plans for transformers, voltage regulators, and load-tap changers.
o The test plan can be created on the PC and then transferred to the ATRT.
o A test plan can be used to quickly test transformers and obtain test results,
percentage-error calculation, and Pass/Fail results.
• Export test records in Microsoft Excel format.
• Retrieve test records stored in an ATRT.
1.1 System Requirements
The TTRA-S2 software has the following minimum system requirements:
• PC running Microsoft® Windows® XP or Windows® Vista

Before using the program, the system configuration parameters should be reviewed and
changed as required. To configure the program settings:
1. Make sure the TTRA-S2 software is running on the PC.
2. Click on the System-Config menu. The following window will be displayed:
a. Communications
If the ATRT is connected to the PC via the USB interface, make sure that the “USB

you change will only stay active for the current session and will be reset the next
time you run the software.
Type the number of tests that need to be run in the “Test Limit” input box. The test
limit defines the number of tests to be used in the transformer test plan. For
example, if the transformer has 10 tap positions, the test limit should be set to 10.
c. Test Plan Path

4.0 WORKING WITH TEST RECORDS
The TTRA-S2 software can be used to retrieve test records from the ATRT or from the PC hard
drive. Once a test record is retrieved, you can change the record header settings, print the test
record, change the H Voltage, X Voltage, H Tap, and X Tap values, and save the record to the
hard drive.
If the H Voltage and/or X Voltage values are changed, the TTRA-S2 software will
automatically re-calculate the calculated ratio and deviation.
NOTE
4.1 Retrieving Test Records From an ATRT
To retrieve a test record from an ATRT:
1. Make sure the TTRA-S2 software is running. Connect the ATRT to the PC via either the
RS-232C port or the USB port and turn on the power.
2. From the Retrieve or File menu select Retrieve Test Record From Device.
3. A window will appear listing a directory of all the test records stored in the ATRT’s
memory as shown:
4. You can select a test record to be retrieved by clicking on the test record number. The
selected record will be highlighted. You may select multiple records by holding down the
[CTRL] key and clicking on the record numbers. All selected records will be highlighted.
You may de-select a selected record by holding down the [CTRL] key and clicking on the
selected record number a second time. To select all of the test records, click on the
“Select All” button.
5. The “Filename Prefix” input field allows you to enter a word that will be used as part of
the filename for the stored record on the PC hard drive. When a test record is retrieved
from an ATRT and stored on the hard drive, the filename is in the following format:
