Vanguard Instruments TRI-PHASE

 VAN-TRI-PHASE True Three-Phase Transformer Turns-Ratio Tester



The Tri-Phase is a true three-phase transformer turns-ratio tester designed to
conform to the IEEE C57.12.90 measurement standard. The Tri-Phase generates
and outputs a three-phase excitation test voltage to the three transformer
primary windings. The induced three-phase secondary voltages are sensed,
and the transformer turns-ratio is calculated.
The Tri-Phase can measure turns-ratios from 0.8 to 15,000.
The three-phase turns-ratios, excitation current, and phase angle
readings are displayed on the units LCD screen. Since a three-phase voltage is
used to excite the transformer windings, the Tri-Phase can detect and measure
turns-ratios of any transformer type, including phase-shifting transformers.

The Tri-Phase can be used as a stand-alone unit or can be computer-controlled.
