Vanguard’s new TRI-PHASE is a true 3-phase transformer turns ratio tester designed to conform to the IEEE C57.12.90 measurement method. The TRI-PHASE outputs a 3-phase excitation test voltage to the three transformer primary windings. The induced 3-phase secondary voltages are sensed and the transformer turns ratio is calculated. The TRI-PHASE is capable of measuring turns ratios from 0.8 to 15,000. The 3-phase excitation current, phase angle readings along with the turns ratios are displayed on the built-in LCD. Since a 3-phase voltage is used to excite the transformer windings, the TRI-PHASE can detect and measure turns ratios of any transformer type. The TRI-PHASETM can easily measure the turns ratio of phase-shifting transformers where other 3-phase transformer ratio testers cannot.
