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.

AC Fuel Flow Signal Generator
TA-100
-
The TA-100 signal generator was designed to facilitate testing of aircraft fuel flow indicators that require two input signals designated as “Drum” and “Impeller”. This generator provides both signals so as to provide a direct interface to the fuel flow indicator under test. The generator also provides switched power out to the unit under test as well as a 5v source for testing the bezel lighting. The original design was built around the requirements for the AMETEK series indicators (pn: 10171 series). This generator simulates a reference and a time delayed signal of appropriate amplitude for an indication of up to 1200pph for the indicator under test. The “PPH Select” switch provides fixed signal delays representing 0, 200, 400, 800, 1000 and 1200pph flow rates respectively, this provides the mechanic with an expedient check of the indicators accuracy. The “PPH Adjust” control allows the mechanic to vary the signal delay throughout the full range and serves as a good method for checking of pointer smoothness from stop to stop. The unit’s front panel also provides test jacks to monitor the “FDR Output” as well as the drum and impeller signals. The TA-100 requires only 28Vdc to operate. This generator provides a very economical approach to any repair facility or flight department as it becomes an alternative to purchasing two bench top signal generators. The TA-100 generator at the very least can provide a simple functional test and eliminate the high cost of exchanging an indicator as a function of troubleshooting the aircraft system.
