1.0 INTRODUCTION
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 turns-
ratio 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.
