Frequently asked questions
What does Wirescan LIRA measure?
Wirescan LIRA uses line impedance resonance analysis to assess cable condition and identify irregularities such as local changes, damage or degradation along the cable system.
Is LIRA a destructive cable test?
No. LIRA is used as a non-destructive diagnostic method, making it useful for condition assessment, investigation work and maintenance planning.
Can Reynard help interpret the LIRA results?
Yes. Reynard can support the measurement setup, data review and interpretation so the findings can be translated into practical project decisions.
Does LIRA replace high-voltage withstand testing?
No. LIRA is a diagnostic method and is often complementary to other cable testing activities. Reynard can advise which test approach fits the objective.
What information is needed for a LIRA request?
Helpful details include cable type, voltage level, cable length, installation history, known issues, access points, test objective and whether the cable is energised or de-energised.
Can Wirescan LIRA be used for offshore cable projects?
Yes, subject to project conditions. Reynard reviews access, logistics, safety requirements and documentation before confirming the rental or service scope.
