STX40 Cable Fault Locator
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.
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.
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.
With the STX40 you will always have the right tool at hand, even on difficult-to-find faults.
About the product
With its single rotatory knob or touch screen control and its fully automated motorised HV switches, the STX 40 is the most convenient and most powerful portable fault location unit in the market.
It is ideally suited for all essential fault locating tasks, such as analysing, prelocating and pinpointing of faults on low voltage and medium voltage XLPE or EPR insulated cables. With its 40 kV DC source and a potent high frequency burner it is also highly effective on PILC cables.
7 built-in fault locating methods
The STX40 redefines the state-of-the-art: as a complete package it comes with all necessary fault locating components fully integrated in a single robust housing. The STX is the only system in its class with 7 fault locating methods built-in:
- Insulation resistance testing
- Time Domain Reflectometry (Radar)
- HV DC proof testing (DC hipot)
- Burning
- TDR-based prelocation and additionally transient prelocation methods
- Surging/Thumping in multiple voltage stages
- Sheath testing and Sheath fault pinpointing
Made for demanding outdoor use
Fault location systems have to meet steep requirements to be considered truly portable and outdoor-ready for use in the field. Units must be lightweight, rugged, very mobile in adverse terrain and as compact in size as possible. Units must also be operable in rain as well as in very bright daylight conditions with intense sunshine. With its IP43 rating, low weight and pneumatic tyres, the STX40 is the only fault locating unit in its class with this high degree of outdoor-readiness.
The STX40 also has a very wide operating temperature range. No matter whether you are fault locating somewhere in the desert in +55°C or somewhere near the polar circle in -20°C, no matter whether you are up in the mountains at high altitudes where the air is thinner or somewhere in the jungle in humid or tropical conditions – the STX40 is built for all climates.
