Tap Changer Analyzers & Winding Ohmmeters
-
Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

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.

onTAP’s THREE TAP CONNECT JTAG
-
Connect the TAP CONNECT JTAG Controller to your application with either the Xilinx ribbon cable, flying leads, or Altera style adaptors. The onTAP TAP CONNECT Controller automatically senses and adjusts to target I/O voltages and interfaces to devices operating at 1.8 to 5.0 VDC for the standard controller, or 0.99 to 3.6 VDC for the low voltage controller, using the VREF voltage from the target chain. If there is no VREF available, you can set the voltage for the target application from the TAP CONNECT Controller. This facilitates easy configuration to many different JTAG ports, which is helpful in design and manufacturing.
