Cable Fault Location Test Systems

As the supply of electrical energy is getting more and more important for our society, it is necessary to make sure that power supply system works without any problems. Cables are  frequently used for the distribution of the electrical energy. Although the cables are highly developed, there are sometimes malfunctions in the cable system. To keep the consequential damages as small as possible, trained staff and efficient equipment is needed.

BAUR cable fault location instruments and systems are applicable to all types of cables ranging from 1 kV to 500 kV and all types of cable faults such as:

  • Short circuit faults
  • Cable cuts
  • Resistive faults
  • Intermittent faults
  • Sheath faults
  • Water trees
  • Partial discharges

We distinguish between two types of cable fault location:
  • Pre-location
  • Pin-pointing


BAUR Pulse Reflection Test Set, IRG2000
Model shown IRG 2000

Time Domain Reflectometer - BAUR IRG Series

The Pulse Reflection Test Sets IRG Series for cable fault pre-location using the Time Domain Reflection (TDR) method on low, medium and high voltage cables. It can also be used on live cables up to 400 V. Further fault location methods are available with the application of the appropriate coupling device. Its measuring ranges enable pre-location on cable lengths from 0 m to 65 km (0 to 213,000 feet).

 

Model shown SSG-2100

 

Surge Voltage Generator - BAUR SSG Series

BAUR's Surge voltage generators are used for pre-locating as well as for pin-pointing of high and low resistance faults in power cables. The stored energy of the high voltage capacitors is fed at intervals into the faulty cable. This causes an acoustic noise at the fault position which can be detected with a ground microphone and an audio frequency receiver.
  • Models with high surge voltage up to 32 kV
  • High surge energy in each voltage range
  • Automatic discharging device
 

STG 600

 
 

BAUR STG-600 Low Voltage Cable Fault Location System

The low voltage cable fault location system STG 600 includes a surge generator, a high voltage source for testing and precise location of sheath and cable insulation faults. The STG 600 is a multifunctional cable fault locating set especially designed for low voltage

  • Optimized unique fault location system for low voltage networks
  • Low weight, portable
  • High surge energy 600 Joule (optional 1000 Joule)
  • Output voltage adjustable in 0.1 kV steps

ATG 6000


Burn Down Transformer - BAUR ATG Series


The burn down transformer ATG Series is used to decrease the impedance of cable faults in medium and low voltage cable networks. The short circuit proof transformer provides a maximum voltage of 10 kV (ATG 2) or 15kV (ATG 6000) and is enclosed in a fully encapsulated 19“ housing. Additionally in each step voltage and current can be limited separately via potentiometer.
  • Models with output voltage up to 10 kV DC
  • Maximum power consumption 2.2 kVA
  • Optimized output voltage ranges
  • Electronic control of voltage and current 
 

 

Shirla Fault Location System

Shirla


Shirla sheath testing and fault location system

BAUR's new revolutionary and unique device is used for cable and cable sheath testing, fault pre-location as well as for sheath fault pin pointing according to the step voltage method. Analyses are done automatically and the results are displayed digitally. For cable fault pin pointing according to the step voltage method, shirla applies a defined DC pulse pattern and the step voltage can be picked up by using the KMF1 or UL receiver set.

  • Cable and cable sheath testing up to 10kV
  • Resistance measurement
  • Cable and cable sheath fault pre-location with high precision bridge
  • Cable sheath fault pin pointing

Compact Cable Fault Location System, BAUR Syscompact Series

Model Shown, Syscompact 2000M

Compact Cable Fault Location Systems - BAUR Syscompact Series

The SYSCOMPACT series is a multi-functional cable fault location system in a modular 19” plug-in design. The surge and test generator is designed for testing of cables and cable sheaths and for the precise location of high-resistance and intermittent faults. The SYSCOMPACT 2000 is used preferably in low and medium voltage networks for locating faults on cables up to 65 km in length.
The integration of established fault pre-location methods SIM-MIM and Impulse Current Method enables the precise location of high and low-resistance as well as intermittent faults using the IRG 2000 echo meter.

Test Methods
