TRI-PHASE OPERATING™ INSTRUCTIONS 1.0 Introduction 1.1 Applicability This manual is applicable to the True Three-Phase Transformer Turns-Ratio (TRI-PHASE™) Tester model made by Vanguard Instruments Company, Inc. 2.0 General Description The TRI-PHASE™ is a true three-phase, field-portable, automatic transformer turns-ratio test instrument designed to conform to IEEE C57.12.90 measurement method.
TRI-PHASE OPERATING™ INSTRUCTIONS 3.0 Functional Description The TRI-PHASE™ measures a transformer turns-ratio from its windings by applying a 3-phase test voltage across the primary (H) winding and sensing the induced voltage on the secondary (X) winding. The measured voltage ratio between H and X is virtually the same as the turns-ratio of the windings because of no load on the windings during testing. The TRI-PHASE™ is capable of testing either single phase or three phase transformers.
TRI-PHASE OPERATING™ INSTRUCTIONS 3.0 Functional Description (continued) • The TTRA software application is compatible with Microsoft Windows XP, and Microsoft Windows Vista (see section 11.3 for more details). • Capable of raising or lowering the Load Tap Changer (LTC) tap position from the TRIPHASE™ front panel with the built-in LTC controller (see section 24.0 for more details). 4.0 Principles of Operation The TRI-PHASE™ measures transformer turns-ratios (using the ANSI/IEEE C57.12.

TRI-PHASE OPERATING™ INSTRUCTIONS 11.0 Special Features 11.1 LCD Contrast Control To darken the LCD display, press and hold the “V Contrast” switch for more than two seconds. To lighten the LCD display, press and hold the “W Contrast” switch for more than two seconds. 11.2 Test Voltages The TRI-PHASE™ has three selectable test voltages: 8Vac, 40Vac, and 100Vac. The TRIPHASE™ has two selectable test frequencies, 50 Hz and 60 Hz. Refer to Table 19.0 for test voltage selection. 11.
TRI-PHASE OPERATING™ INSTRUCTIONS 12.0 Typical Cable Hook Up Configurations Always ground the TRI-PHASE™ with the provided ground cable contained in the cable set before connecting H and X cables. Ground the transformer bushings before connecting test leads to transformer. This procedure prevents inducing any voltages into the TRI-PHASE™. All transformer buss connections must be removed and transformer isolated before performing testing of transformer.
