Circuit Breaker Analyzers & Timers
CAT Handheld Series
-
When it’s not practical to use conventional robust circuit breaker analyzers, a handheld circuit breaker analyzer and timer may come handy. DV Power has developed a unique CAT Handheld series. It is specially designed for testing of circuit breakers with one break per phase. Their compact and ergonomic design can provide a wide range of features and reliable operations in low, medium and high-voltage substations or in industrial environments.CAT Handheld series consists of two models, CAT-P and CAT-H. Both of them have a large (5,7 in) colored touch screen display. Because of that, test results are visible in dark places as well as in bright sunlight.Powerful internal Li-Ion battery of the instruments can last up to 8 hours of testing without recharging.CAT Handheld series records:main contacts operating times,contact synchronization,sequence time,a resistance of pre-insertion resistors,open and close coil currents,main contacts bounce time,auxiliary contact time,DC Voltage.Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by triggering signal from current clamps connected to circuit breaker coil.CAT-H is capable of performing a coil control, while this feature is optional at CAT-P instrument. In contrast to CAT-H, CAT-P instrument can execute “First Trip” test.Both instruments display numerical and graphical results. Because of that, a user can easily overlay up to 4 records in the graphical form and make a quick on-site analysis of potential defects.A user can download test results to a PC via Bluetooth interface for more detailed analysis using DV Win software.

VUV Spectroscopy Detector
-
All gas phase molecules absorb strongly in the vacuum ultraviolet region (120 – 240 nm), yet application of VUV absorption technology to routine analytical detection and measurement has not been addressed…until now. The VGA-100 is the world’s first benchtop VUV spectrometer. It is a universal mass-sensitive gas chromatography detector that provides both qualitative and quantitative data. The strong absorption of gas phase molecules in the VUV spectrum provide excellent sensitivity, and the compound-specific absorption spectra provide unparalleled selectivity.

First approach is to generate the high frequency directly, at the fundamental, using an oscillatortuned on the desired frequency. Few sensitive issues appears here due to high working frequency as, stability, jitter, phase noise, pulling, pushing, low output power, and cost of the active component to meet the performances

Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.

In-Circuit Tester Integration
-
The benefits of boundary-scan are noticed in all phases of a product life cycle. By coupling the power of Corelis boundary-scan tools with an In-Circuit Tester (ICT), a complete, integrated solution is available that offers the best advantages of both technologies.Boundary-scan operates as the perfect companion to ICT. Boundary-scan is capable of testing areas of printed circuit board assemblies that are difficult to access due to physical space constraints and loss of physical access, which is often due to fine pitch components such as Ball Grid Array (BGA) devices. Conversely, the ICT is able to check the non-boundary-scan compatible portion of the unit under test (UUT) such as analog.
