Wirescan LIRA® for Cable Monitoring & Diagnostics of Insulated Power Cables

Unique value proposition (UVP)

Wirescan's LIRA® One is a portable, non-destructive diagnostic system for insulated power cables - LV to UHV, underground and subsea. In a single on-site measurement, it locates faults to within 0.1–0.3% of cable length and reveals a wide range of hidden issues - hot spots, mechanical damage, insulation degradation, water ingress - building a condition baseline that can be tracked over the cable's lifetime.

For assets needing ongoing insight, the same core technology extends to LIRA® Live, continuous real-time monitoring for energised cables. Together they give operators cable health intelligence from commissioning through decades of operation - used across offshore wind, transmission interconnectors, and industrial power infrastructure.

Key Benefits

A single on-site measurement gives operators immediate fault location - accurate to within 0.1–0.3% of cable length - and a full condition assessment, without the electrical stress that destructive tests like VLF and Hipot put on ageing insulation.
One scan reveals a wide range of hidden issues along the entire cable length - hot spots, mechanical damage, insulation degradation, water ingress, and hard faults - closing the blind spots that limit reach-constrained methods like Time-Domain Reflectometry.
Each measurement builds a fingerprint that can be compared over time - from commissioning through decades of operation - and for assets that need visibility between assessments, the same core technology extends to LIRA® Live for continuous, real-time monitoring.
