Cable Sheath Testing and Fault Location
Shirla is used for cable and cable sheath testing, as well as for pre-location and pin-pointing of cable faults. Pre-location is based on a measuring bridge principle according to Murray and Glaser. The measuring bridge is dimensioned and specifically designed for power cables, but also enables pre-location for control and lightning cables. Zero balance and evaluation take place automatically.
