STX40 Cable Fault Locator
Portable standalone cable fault location unit
Portable standalone cable fault location unit
Key Benefits
- Get the job done in all weathers and challenging terrain
- Find cable faults quickly and easily with convenient automated controls
- Always have the right tool at hand with 7 built-in testing methods
- 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.
Description
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.

Frequently Asked Questions
Can the STX40 also locate faults in paper-lead cables?
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.
