Applications

Wirescan’s LIRA® cable diagnostic tool are designed to locate faults, degradations and deviations, monitor cable conditions real-time and estimate the remaining life time. Cable operators will take advantage of the technology during routine maintenance, when a cable problem occurs, during quality control tests and when assessing the conditions of installed cables.
 
 
Features

• Best cable monitoring and diagnostic system available.
• Sensitive to small degradations and defects.
• Accurate hot-spots and deviation locations.
• Non intrusive and non destructive.
• Measurement of energized cables from 2011*
• Only one access point needed for measuring.
• Pre-study/simulation of cable data and defects.
• Applicable on multi-segment systems with different cable types.
• LIRA® is less influenced by noise and therefore more sensitive and accurate.
• LIRA® performs a power spectrum analysis of impedance phase and amplitude – an advanced detection method of abnormal conditions.
