TELEFLEX® VX-PT V2
Three-phase time domain reflectometry
As with all Teleflex reflectometers, the VX is specially de-signed for the rapid processes of power cable fault location. The new hardware offers significantly improved parameters including sampling rate, pulse width and pulse amplitude, resulting in a wider range, higher resolution and above all, improved measurement.The ΔU Trigger technology always provides the perfect trig-ger timing. The ARMslide method records 15 traces in one shot and allows the selection of the best trace, especially for wet and long cables. The ProRange function allows for range-based gain adjust-ments, displaying distant reflections with the same ampli-tude as from short distances. Data can be easily transferred using the USB interface, either in MeggerBook Cable software format, a PDF or directly to a printer.The Teleflex VX can also be integrated into a system via the Ethernet, which allows for simple remote control in offshore applications and ROVs.
The Teleflex® VX-PT V2 is a portable, stand-alone, three phase time domain reflectometer (TDR)
- Bright and large display
- Easiest operation via self guiding and explaining menus
- ARM Multishot technology
- Automatic storage of all results
- Supports all existing prelocation technologies
- Automatic detection and display of cable end and fault position
The Teleflex® VX-PT V2 is a portable, stand-alone, threephase time domain reflectometer (TDR) designed for fault location on power cables encompassing all voltage levels, such as low voltage (LV), medium voltage (MV), and high voltage (HV) applications. Its primary focus is on long HVAC and HVDC installations, whether they utilise paper insulation or solid dielectric insulation.
With its straightforward graphic user interface, featuring a single rotary knob (jog dial) and the well-known piechart navigation, the Teleflex® VX-PT V2 ensures operator comfort and enables effcient operation. The device incorporates a large, bright color touchscreen that enhances ease of use and facilitates quick and accurate readings
In addition to its comprehensive fault location features, the Teleflex® VX-PT V2 supports proper fngerprint measurements. The ability to perform accurate fngerprinting proves particularly benefcial during the
commissioning of newly installed long HV cables, as it establishes an impedance baseline. This baseline serves as a crucial reference for future comparisons in the event of cable faults.
When combined with a surge generator and suitable separation devices, the Teleflex® VX-PT V2 supports all HV prelocation methods (e.g., ARM, ICE, DECAY etc.). Its adaptive trigger technology ensures optimal timing of TDR measurements for most accurate results.
