DV-Power – TRT3x True Three-Phase Turns Ratio Tester – Single and true three-phase voltage up to 100V

Datasheet - DVPower - TRT3x


When it comes to choosing a transformer turns ratio tester, TRT Standard series offers some of the most advanced instruments with LCD display out in the market. Each model measures transformer excitation current and phase shift, performs automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. Furthermore, they have a built-in true three-phase power source. Because of that, TRT Standard instruments can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.
