Technology


LIRA® is a system for real-time diagnosis and condition based monitoring of installed electric cables. The system monitors the global degradation of the cable insulation caused by harsh environment conditions (high temperature, humidity, radiation) and detects local degradation of the insulation material due to mechanical impacts or local abnormal environmental conditions.
 
The system consists of “off the shelf” hardware plus connection devices and proprietary software performing the failure analysis, degradation analysis and cable simulations. LIRA® measurements are recorded on the system and can be played back and analysed off-site. Reports in MS-Excel format are automatically generated. The recorded measurements can be stored as reference information (fingerprints) for later comparison with repeated measurements. The identification of new damage to the cable can thus be monitored and recorded.
 
 
Key Characteristics:

  • LIRA® can measure cable length ranges from less than 50 meters to several hundred kilometers, depending by the cable design and electric attenuation.
  • The LIRA® technology is a non-destructive test method, and will not damage any part of your cable or any equipment connected to the cable.
  • The LIRA® technology is based on the transmission line theory, through the estimation and analysis of the complex line impedance as a function of the applied signal frequency.
  • LIRA® can monitor the global, progressive degradation of the cable insulation, cable stealth and cable conductor caused either by to harsh environment conditions, or mechanical stress.
  • LIRA® is especially sensitive to small changes in the insulation material, which allows an early indication of challenged areas, detecting and localizing single and multiple faults and their severity.
