Line resonance analysis (LIRA) 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.
Your advantages: Benefit from our know-how
- Knowledge of ageing mechanisms in high-voltage cables
- Condition recording of the remaining service life
- Better planning of cable replacement through reference measurements (footprints)
