Line resonance analysis (LIRA)

The LIRA process creates the basis for possible long-term use of the cable systems over the normal operating life of 40 or 50 years:

• Slow aging process of cable systems
  
• Provides diagnostic methods for status detection and residual life without high-voltage testing
• Axpo has measurement experience and can use measurement data as reference values.

1. Knowledge of ageing mechanisms in high-voltage cables
2. Condition recording of the remaining service life
3. Better planning of cable replacement through reference measurements (footprints)
