shirla Cable sheath testing and fault location device

The shirla sheath test and fault location device is used for cable and cable sheath testing, and for the pre-location and pin-pointing of cable sheath faults and cable faults due to earth contact.

Manufacturer: BAUR GmbH (Austria).


The fault pre-location is based on the measuring bridge principle according to Murray and Glaser. The measuring bridge is dimensioned specially for power cables, but also enables pre-location for control and lighting cables. Zero balance and evaluation take place automatically. The fault distance is shown in meters. Various cable sections can be entered, thus increasing the accuracy of the measurement.

For fault pin-pointing, shirla generates a pulsed voltage, thereby permitting the use of the step voltage method. Using the "Step voltage” set of the protrac® pin-pointing system, cable sheath faults and other faults due to earth contact can be located quickly and accurately.
  • Fault pre-location and pin-pointing in a single device
  • Data export via USB interface
  • Mains and battery operated
  • Simple operation and intuitive user interface
