STX40
Get the job done in all weathers and challenging terrain
The STX40 is an outdoor unit with exceptional all-terrain mobility, for easy and dependable on-site use in all conditions. The unit is weatherproof with a rating of IP43. It can be easily transported in difficult terrain due to its low weight, pneumatic tyres and low center of gravity: compared to its predecessors it weighs 80 kg (176 lbs) less.
The sunshine-proof display with anti-glare coating keeps the user interface clearly visible even in intense sunshine, while its wide operating temperature range provides reliable operation whether you are in the desert in +55°C or somewhere near the polar circle in -20°C.
Find cable faults quickly and easily with convenient automated controls
Unlike older units with their extreme overload in terms of knobs, buttons, levers and variacs, the STX40 is a fully automated system: just tell the system what to do and it will set itself up automatically and accurately without any further user intervention.
Navigating the menus is straightforward and self-explanatory thanks to STX40’s intuitive graphic user interface, which can be operated either by a single rotary knob or via the display’s touchscreen function.
Both the selection of all high voltage operating modes, and the execution of all high voltage functions and methods are automated via software-controlled motorised switches. That means the STX40 offers the same convenience and comfort of a centrally controlled cable test van.
Always have the right tool at hand with 7 built-in testing methods
Since low impedance faults and high impedance faults have different specific characteristics, not every fault location method is applicable to every fault. To effectively find faults on underground cables, the best approach is to have a whole toolbox of various methods which complement one another.
To help you achieve this, the STX40 provides seven different testing methods fully integrated in a single robust housing. The unit has an in-built TDR of the Teleflex® type for time domain reflectometry, with an insulation testing unit, a very powerful high voltage DC source, a multi-stage surge wave generator (thumper) for pinpointing with the digiPHONE +2, a high frequency burner for fault conversion, and a set of standard radar-based and transient prelocation methods.
About the product
- True portable outdoor-ready unit, IP 43
- Very easy to use 'turn and click' single rotary knob interface
- Surge/thump energy 2000 Joules
- DC testing up to 40 kV, surging/thumping up to 32 kV, burning up to 40 kV
- Pre-location methods: Inductive ARM with multishot, ICE, and DECAY
- Built-in safety circuits for earth connection monitoring (F-Ohm) and touch potential monitoring (F-Voltage)
- Full TDR control of all HV functions
The STX40 portable fault location system is the most powerful of its kind in the market. It is ideal for proof testing, analyzing, pre-locating and pinpointing faults on extruded low voltage and medium voltage XLPE- and EPR-insulated cables. With its 40 kV DC source, and a potent high frequency burner, it is also highly effective on PILC cables.
The STX40 is fully automated with motorized HV switches controlled by either the rotary knob or the industry-grade color touch screen.

Software and firmware updates
STX Operating Firmware
STX Operating Firmware
latest version
For update packages that contain only one rpm file and therefore only require an update of the operating software, proceed as follows:
1. Copy the zip file to the main directory of a USB flash drive.
2. Unzip the zip file to obtain the rpm file in main directory of the USB flash drive.
3. Insert the USB flash drive into the USB port of the powered-off STX 40.
4. Turn on the STX 40.
Result: The new version of the operating software is automatically detected and installed at start-up.
Do not turn off STX 40 during the update.

The setup file below is suitable for the installation of both MeggerBook (full version) and MeggerBook Lite (free limited version).
When started with after adding the electronic license key into the installed software, the software starts as MeggerBook full version which allows for easy and comprehensive data evaluation, data archiving, cable management and report creation. A personal quotation for a certain number of licenses can be requested here . The new electronic license key allows for 3 devices to have MeggerBook full version installed on them.
The dongle key licenses from older versions of MeggerBook are not supported with this newer version. Updated electronic license keys can be requested here for previous customers.
Without the required software license key the software starts as MeggerBook Lite which allows for seamless report creation and offers some of the features as the full version while limiting the data storage options as follows:
• Measurements, analyses and reports are not permanently stored in the database
• While cable import and storage are not limited, a maximum of 5 cables can be created using the cable editor of the Lite Edition
At this time, the software can handle the measurement and test data of the following Megger devices:
Test vans: Centrix, Centrix City, Compact City, R30, Variant
Test systems: VLF Sine Wave 45 / 62, VLF CR 40/60, TDS 40/60
TDRs: Teleflex VX(-P), Teleflex SX
Note for test systems VLF Sine Wave 45 and VLF Sine Wave 62:
Data of these test systems can only be imported into the software, if the test systems is equipped with firmware version 3.14 or higher. The latest firmware can be found here (VLF Sine Wave 45) and here (VLF Sine Wave 62).
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.
