Helmholtz Coils
-
Helmholtz-Coils are especially designed to generate precisely defined magnetic fields from DC to the upper end of the audio frequency range and beyond. The generated fields are in a strongly linear relation to the coil current. The field- strength can be calculated exactly by analytical (or numerical) methods, based on the coils' geometry, the number of turns and the coil current.

Round Wire Coil Inductors
-
Round wire coil (RWC) inductors come in six platform sizes and enable the highest efficiency of any SMT inductor through the use of a low loss ferrite core material which minimizes AC losses and also eliminates thermal ageing. The use of round magnetic wire instead of rectangular flat coils enables a lower cost while still maintaining a low DCR and small footprint. The platforms have passed the AEC-Q200 stress test qualification proving the designs robustness and suitability to difficult environments but the parts are not IATF certified. The platform range from 7.6×7.4×6.4mm to 26x26x15mm and are suitable for a wide range of applications and markets including communications, computing and industrial.

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.
