  • Mechanical Force Gauges

    IMADA, Incorporated

    Imada mechanical force gauges are highly accurate instruments used to test the quality, strength or functionality of component parts or products. Imada mechanical force gauges check both compression and tension (push or pull). Peak force can be captured using the peak indicator needle and the tare ring compensates for the weight of attachments. Imada force gauges are constructed with a heavy-duty metal case and all metal components to enable them to retain their calibration for years with proper care. These mechanical force gauges never need charging or batteries and are intrinsically safe in hazardous environments.

  • Transformer Test Equipment

    IBEKO Power AB

    DV Power test instruments perform various diagnostic tests on power and instrument transformers. Even more, a unique feature is a condition assessment of on-load tap changers. Performing a transformer test before their breakage can be crucial.Test instruments are portable and enclosed in durable metal cases. Also, the 19” rack-mounted version suitable for factories is available as well.Applications supported by DV Power transformer test equipment include:Winding resistance measurement (IEC 60076-1)Analysis of on-load tap changers (IEC 60214-1)Heat run test (IEC 60076-2)Automatic transformer demagnetizationTurns ratio measurement of power and instrument transformers (IEC 60076-1)Excitation current measurementPhase angle measurementTransformer vector group detectionDemagnetization status verificationAll of the above-mentioned measurements are performed with the highest accuracy.The advanced DV-Win PC software collects both numerical and graphical results. As a result of that, these features provide an easier and more efficient analysis. After the test, DV-Win software generates a test report with a single click. Furthermore, a user can easily customize the test report and save it in different formats, such as XLS or PDF.Finally, the analysis of on-load tap changers is performed by the new method called dynamic resistance measurement (DRM). This is a non-intrusive method. Therefore, it allows detecting problems in on-load tap changers without disassembling them.

  • Fatigue Testing And Certification

    Hill Engineering, LLC

    Fatigue engineering is subject to uncertainty, and data from well executed tests are used to validate conclusions made by analysis and to provide a basis for structural certification. Our staff have extensive experience in testing materials and components under slowly varying, static loads, and under rapidly varying cyclic loads. Tests under static loads are used to assess material properties or to assess the load-deformation behavior of structural components. Tests under cyclic loads provide time to crack initiation, time to failure, or measurements of crack growth over time. We have extensive experience in measuring fatigue crack growth behavior in metallic materials. Past programs have measured crack growth with microscopy and photogrammetry at the surface, cracked area with direct current potential drop, and through-thickness crack profiles with quantitative fractography. By assessing crack growth with a variety of experimental methods, we enable robust analysis validation for cases of complex cracking. Our capabilities in fatigue engineering allow for careful design of a fatigue test program. Whether the tests use constant amplitude loading or an irregular loading spectrum, we specialize in engineering the test that meet your needs. Much of our experience is in non-standard test programs, which require engineering to optimize the test setup. Few others match our capability and experience in fatigue test engineering.

  • Break Strength Testing

    National Technical Systems

    To determine the failure point or break strength, you will need to define what a break is (break detector). Generally, there are two common types of breaks: the sharp break is referred to the measurement when load or force drops by 5% from its peak load measurement. A percentage break is another form of break and is generally determined by the sample material and its relationship to load degradation from a peak load measurement. A plastic material will likely have a load drop of 5%, but not represent a break. In this case, a percentage break would need to be applied. In a tensile test, the breaking load is the break strength.
