Kinectrics Expands Cable Assessment Capabilities with LIRA®

September 29, 2017

Kinectrics is pleased to announce that LIRA® (Line Resonance Analysis) has been added to the portfolio of cable condition assessment services offered by its Electrical and Safety Testing group.
LIRA® is a non-destructive low voltage assessment technology which utilizes Frequency Domain Reflectometry (FDR) to detect, localize, and characterize subtle impedance changes in a cable system.
FDR is based on the interaction of electromagnetic waves with conductors and dielectric materials as they propagate along the cable. The technique uses the principles of transmission-line theory to locate and quantify impedance changes in the cable circuit. These impedance changes can result from connections, faults in the conductors, or degradation in the cable polymer material.  Used in conjunction with other advanced diagnostics, this tool can shed light on bulk (global) insulation condition, as well as localize defect identification.
Kinectrics is a leading provider of EHV/HV/MV/LV cable condition assessment and Partial Discharge (PD) testing services using the most advanced technologies available globally.
