Turns Ratio Testers
TRT Advanced Series
-
TRT Advanced series is the newest DV Power solution for transformer turns ratio measurement. Besides its main application, each turns ratio tester from this series also measures transformer excitation current and phase shift. Furthermore, all models perform automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. They have a built-in true three-phase power source. For that reason, they can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 500 V AC, depending on the model. With the highest test voltage 500 V AC, TRT500 provides the most accurate turns ratio testing of power transformers used in power generation and transmission. The output test voltage of TRT500 can be boosted to 5 kV AC using the external CVT20 extension transformer. This application is specially designed for testing turns ratio of capacitive voltage transformers. The other three models, TRT400, TRT250, and TRT100 can output up to 400 V, 250 V, and 170 V respectively. The low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT500 is equipped with a large 10.1” graphical touch screen display. Other models, (TRT400, TRT250, TRT100) have 7” graphical touch screen display. Besides making the interface much more user-friendly compared to older turns ratio testers, it also brings certain options that were previously available only with DV-Win software. The most important are test templates and automatic test mode. Users can simply create test templates, store them in the instrument’s memory, and load when in the field with just a few clicks.This turns ratio test set, as well as all other DV Power turns ratio testers, has a built-in tap changer control unit. It enables remote control of an on-load tap changer (OLTC) directly from the instrument. In order to make the most out of this feature, the instrument can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time. Automatic test mode minimizes human errors, which makes the measurement more reliable.

Turns Ratio Testers
TRT Standard Series
-
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.The instruments can output test voltages from 1 V AC to 250 V AC, depending on the chosen model. High test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and extremely low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT Standard series consists of:TRT03 Models (TRT03A, TRT03B, TRT03C) – single-phase voltage up to 100 VTRT3x Models (TRT30A, TRT30B, TRT30C, TRT33A, TRT33B, TRT33C) – single and true three-phase voltage up to 100 VTRT63 Models (TRT63A, TRT63B, TRT63C) – single and true three-phase voltage up to 250 VMore about models differences can be found under the downloads tab, in brochures and comparison sheets.A user can create test templates using the DV Win software and store them in the PC’s memory for later use when in the field.TRT Standard series models have a built-in tap changer control unit. Consequently, it enables remote control of an on-load tap changer (OLTC) directly from the tester. In order to make the most out of this feature, the DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time.
