Extra high resolution along with daylight backlighting and user-determinable color schemes give the graphical display a dynamic quality that helps the operator identify key tracking events.

Trace storage: 100 internal trace memories are available for storing and recalling test results. The tracings can be recalled and displayed for analysis or can be compared to an active display to aid in fault location.Alternatively, the stored results can be downloaded to a computer via a USB interface using TracXpert software and the supplied USB cable. Step TDR function:The dead zone effect of a standard pulse TDR can mask defects near the end, making them undetectable. The addition of a step function on the TDR2050 fixes this problem. Step TDR technology means that the signal is impressed at full strength and remains there until a fault is detected. This makes the step TDR technology perfect for detecting faults near the end that are missed by standard pulse TDR.

VLF Meter M-VLF28 is suitable for cable testing and cable diagnosis. If a fault in the cable networks of the medium and low voltage range causes a malfunction, quick localization is important. Eliminating the supply interruptions is immensely important. Because it saves time, money and trouble. Besides that, the advantages of VLF testing have been confirmed by scientific studies and practical field tests. Also, the VLF test is recommended by the DIN VDE standards and the standardization of the IEEE 400.

Testing medium voltage cables or rotating machines and transformers has never been easier. If a fault occurs, high-tech equipment should be available to perform the necessary measurements. In fact, prerequisite for this is state-of-the-art technical measuring equipment. The VLF measuring device M-VLF28 has manual and automatic test settings. Additionally, the diagnostic sequences offer different operating modes: such as the VLF cable test with symmetric AC voltage. But this is load independent over the whole range. Furthermore, a second option is the test with DC with positive and negative polarity or burning in case of high-impedance faults. Overall, cable sheath test as well as the sheath fault location are possible.

On top, for the discharge of test specimens, a discharge device is available. This device enables both electronic and mechanical discharge of the test specimen. Moreover, the VLF test device can be extended with an internal Tangens Delta diagnostic unit at any time. With a weight of only 14kg the high voltage generator is the smallest device on the market and is perfectly suited for mobile use. At that, a waterproof, shockproof and dustproof IP67 housing protects the M-VLF28. All in all, these features make the VLF Meter M-VLF28 an outstanding cable testing and cable diagnostic device.

TDR Reflectometer: Megger offers you the greatest experience in time domain reflectometry. The method is also known to many of you as Time Domain Reflectometry, or TDR for short. It involves the determination and analysis of travel lengths and reflection characteristics of electromagnetic signals and waves in electrical conductors. Some people know this technology also under the name “cable radar”, because the principle is indeed similar to a conventional radar. The length measurement of cables in the electrical industry was one of the first important applications.

This involves measuring the time it takes for an electrical impulse to return to its origin. If one now knows the speed of propagation in the cable, which also depends on the dielectric, one can directly deduce the length of the cable from the time. On its way one recognizes also many other “events” like, connection, branches or – errors in the isolation or in the conductor caused by break, corrosion and much more besides.

With a pulse width of only 2 ns at a resolution of 0.1 m, the new type TDR 1000-3 time domain reflectometer for cable fault location from Megger features the new “Ultra Fast Pulse” technology. This improves fault location, especially in the near vicinity of metallic data and telecommunication cables. The new auto-setup function immediately recognizes the cable under test and sets all parameters appropriately in a fraction of a second; this saves time and ensures correct measurement results every time. The Trace Hold function allows clear comparison between two routes. The TDR 1000/3 has a large, high-resolution LCD display with white backlighting and various gray scales. This supports the graphical display in identifying the most important events on the track.
