Baur SHIRLA Cable Sheath Testing & Fault Location System
Baur SHIRLA has been designed for cable and cable sheath testing, fault prelocation as well as for sheath fault pin pointing according to the step voltage method.
The special measuring bridge performs measurements according to Murray and Glaser methods. With the integrated high voltage DC source, shirla can prelocate low as well as high resistive cable faults. The measuring principle enables the prelocation of earth related sheath faults and any kind of earth related cable faults in shielded as well as unshielded cables.
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.
Baur SHIRLA Key Features:
- Cable and cable sheath testing with DC voltage up to 10 kV
