Cable fault location
Locate faults quickly, minimise downtimes
It is essential that energy customers are always provided with a reliable power supply – even when our power supply is undergoing further modification. A high-performance power network, where downtimes are as short as possible, plays a crucial role in ensuring security of supply.
Often, faults on underground cables do not just result in the partial or total failure of the power supply. If these faults are not located quickly and accurately, they can also lead to high repair and restoration costs. It is only through fast and precise cable fault location that costs and downtimes can be kept to a minimum.
Cable fault location with BAUR – reliability with system
BAUR’s top quality cable fault location technology has been setting a global benchmark for decades. With more than 75 years of experience in cable fault location, we offer application-oriented solutions for measurement engineers to suit all requirements and budgets – with everything available from a single source.
All of the technologies work together in an uncompromising manner, even in one single system. Supported by the new forward-looking software concept, they are easy to use, making it possible for less experienced operators to also use their system in a professional and efficient manner.
Our products reflect our 75 years of expertise. The BAUR device portfolio for cable fault location covers the entire process in an optimum manner and helps the operator locate faults quickly and reliably. Modular systems and devices are perfectly customised to your individual requirements. Convincing flexibility!
Rectify network faults more rapidly – with innovative software features
In the event of a cable fault, speed and precision can be crucial in minimising downtimes and restoring mains operation. The Smart Cable Fault Location Guide for the BAUR Software 4 provides support for pre-location and pin-pointing. The software can also be linked to the cable database and a geographical information system to narrow down the type and location of the fault as quickly as possible.
Non-destructive and safe pin-pointing
The protrac® all-in-one cable fault location and tracing system combines all the pin-pointing technologies in one device. Together with its user-friendly operation and reliable operator guidance, the protrac® device is an indispensable member of the pin-pointing device portfolio. BAUR also provides help via the app and even protects the cable: the surge current generator can be remotely controlled this way, which means that cable routes are only exposed to the load for a short time during pin-pointing.
Long submarine and land cables for global power supply
More stringent safety requirements cannot be met with traditional cable fault location.
Submarine power cables and long land cables are indispensable for reliable power supply. The protracted downtime of these cables translates into losses in the millions for the cable operator – with the downtime costs growing day on day. Many cable operators therefore invest in a suitable fault location system even before the cable is put into operation, so that the fault can be located straight away. In the event of any damage, the cable downtime is reduced in the long term.
Cable faults
Basic conditions, types of faults
Cable damage can be due to various causes. The most common sources of faults include end of service life and external influences as well as improper assembly. When these types of cable faults occur, the defective spot needs to be detected as quickly as possible and the fault rectified in order to minimise the duration of the failure.
Process steps & methods
The right measurement method counts
The objective of fault location is to locate a cable fault as quickly and precisely as possible so as to provide the ideal basis for fast repair and reconnection. Fault location is carried out methodically following a logical sequence made up of four steps.
Control cables
Here, the focus is on various control cables, e.g. in switchgear, telephone cables, traffic light pre-emption, etc.
Low voltage cable
… voltages up to 1 kV.
Medium voltage cable
… voltages from 1 kV to 36 kV (country-specific).
High voltage connection cable
… voltages from 36 kV (country-specific).
Very long submarine and land cables
Very long cables for voltage transport, e.g. from offshore turbines, to supply power to islands, etc.
