When it comes to choosing a transformer turns ratio tester<\/strong>, TRT Standard series<\/strong> offers some of the most advanced instruments with LCD displays out in the market. Each model measures transformer excitation current and phase shift and 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, rectifiers, arc-furnace, traction transformers, etc.<\/p>\n

The instruments can output test voltages from 1 V AC to 250 V AC<\/strong>, depending on the chosen model. A high test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and an extremely low test voltage of 1 V AC enables\u00a0turns ratio verification<\/a><\/strong>\u00a0of current transformers.<\/p>\n
