About the product
- Simple operation
- Auto setup for instant use
- Ultra fast pulse for near end fault identification
- Trace 'Hold' feature to allow comparison between cables
- IP54 rating offers real life working
- Designed for use on all metallic cable pairs
The TDR1000/3P handheld time domain reflectometer (TDR) is a compact, handheld instrument for locating faults on metallic cables. With built-in blocking filters and fused test leads, it has a minimum resolution of 0.1 m and a 5 km maximum range depending on the velocity factor selected and the cable type.
The TDR1000/3P has four output impedances available (25, 50, 75, and 100 Ω) and a four-way control switch that makes operating the instrument simple and inutive. It also has a velocity factor between 0.2 and 0.99, enabling it to meet any cable test requirements.
The instrument has an 'Auto selection' option that ensures that the most effective parameters are selected depending on the range required, aiding rapid diagnosis of the TDR trace. Dual cursors allow complete flexibility, giving you full control and an instant indication of the distance between two points. A trace 'Hold' feature also allows comparison between conditions, something not seen on most other handheld TDRs. Extra high resolution together with a white-light backlight and gray scale tones make the graphical display vibrant, helping you to identify key events on the trace.

FAQ / Frequently Asked Questions
Old paper-lead cables pose a big challenge when fault locating due to their different physical construction compared to modern solid dielectric cables. Instead of having to deal with carbon and air like in faulted XLPE- or EPR-insulated cables, PILC cables are made of lapped paper impregnated with mass or oil.Breaking down a fluid insulation medium, igniting and stabilising an arc in a fluid, and capturing useful fault traces with the radar is all far more difficult on paper cables than on solid dielectric cables. In particular, breakdown voltages of high resistance faults may be very high, and low resistance faults do occur significantly more often.To be truly effective on paper-lead cables, the fault location system used must have a high DC hipot, sufficient energy for cap discharge, and a modern TDR. With its 40 kV DC hipot, 2000 Joules at 32 kV and a radar with Multishot and de-attenuation features, the STX40 is well-equipped to be successful in finding faults even on PILC cables.
Occupational safety and safe working conditions are paramount for us and our customers. Therefore, Megger products are designed to be the safest in the market. The STX40 is no exception.The unit meets the strict requirements of VDE 0104. Equipped with a ground loop monitoring circuit (F-Ohm) and a touch potential monitoring circuit (F-U or F-Voltage), STX40 is a milestone and is the portable fault location system with the highest safety standards in the market by far.
