  • Current Caliper

    KH23101 - Beijing KeHuan Century EMC Technology Co,.LTD

    The KH23101 current caliper is a toroidal transformer used to measure EMI current. When measuring, the caliper does not directly touch the electrical conductor or the cable under test. The conductor passing through the caliper window is used as the single-turn primary wire of the transformer, and the secondary is designed to be multi-turn. Use with 50 Ω receiving system (such as EMI electromagnetic interference field strength meter or spectrum analyzer). In order to facilitate installation and rapid measurement of EMI current, it is designed as a caliper that can be opened.

  • Cable Electric Resistance Tester

    MR 270 C-A - Schuetz Messtechnik GmbH

    The MR270C-A is specially designed for electric resistance measurements in cable industry applications and inductive loads (transformers, motors). It is perfectly fit both for measuring the meter resistance in connection with a corresponding resistance measurement holding device or for final acceptance control of power cable reels. In the case of cable reels, which often have a cable length of several kilometers, both the compensation of the inductive component and the ability to perform measurements in the presence of high noise levels are important. This also applies to the winding resistance of transformers and motors.

  • Isolated Power Supplies

    Maxim Integrated

    Isolated power supplies generally include either transformers or optical isolators in both the power and the feedback paths. As a result, isolated power supplies are generally more complex in their design than nonisolated power supplies. Maxim''s isolated power ICs accommodate the necessary isolation components, thereby reducing design complexity and cost.

  • Lamp Converters

    PeakTech Prüf- und Messtechnik GmbH

    This AC / AC voltage converter is particularly suitable for use with halogen indoor lights and other low-voltage light sources that require an AC voltage source for supply. There is a safe galvanic separation between mains and low voltage according to the isolating transformer standard. This pre-assembled AC / AC converter is equipped with an overtemperature switch that cannot be reset.

  • Turns Ratio Testers

    TRT Advanced Series - IBEKO Power AB

    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.

  • Current Sense Magnetics

    Pulse Electronics

    Current sense magnetics are used as a low loss method for sensing AC current in a circuit and also provide electrical and safety isolation between the source of the current and the measurement circuit. The key parameters for a current sense transformer are the rms current rating (to ensure it does not overheat in the application) and the safety and voltage isolation (to ensure it conforms to the end-application requirements).
