LineVue™ - Conductor Inspection Tool

The Kinectrics LineVue™ tool assesses the integrity of transmission conductors to help reduce transmission line failures, maintain reliability of service, and reduce safety risks.

Acquiring knowledge of the actual physical condition of a conductor’s steel core is critical for utilities to avoid conductor failure, ensure reliability of service and maintain public and worker safety.

The Kinectrics LineVue™ inspection system is a reliable non-destructive device which measures the remaining cross-sectional area of the steel core wires in Aluminum Conductor Steel Reinforced (ACSR) and Aluminum Conductor Self-Supporting (ACSS) conductors. LineVue also detects any local breaks and deep pits in the steel core wires.

Transmission conductor assessments using LineVue are conducted in the field on energized and non-energized conductors.

Traditional techniques used to assess the condition of transmission and distribution line conductors typically involve a time-consuming, labour intensive process. Field staff are required to remove the circuit from service, install safety grounds, access and remove a long section of conductor at the selected location with a bucket truck before shipping it to a laboratory for a series of tests. 

A new section of conductor must also be installed in place of the old one.

Sample sites are typically restricted to only one or two locations making the overall sample size very small. LineVue permits assessment of much larger sections of conductor, for example, multiple spans at more remote locations that may be inaccessible by bucket truck.

By enabling measurement of a larger sample size, LineVue is more cost-effective, and provides utilities with a higher degree of safety assurance and condition information

Condition assessment data is also available to the utility during the test, followed by detailed printed reports thereafter. 

The LineVue on-board high-resolution camera produces a visual record of the outer aluminum strands to inform utilities of broken strands as well as potentially identify the possible source of damage e.g. vandalism, wear and tear, and manufacturing defects.                 

A new model of the Kinectrics LineVue™ device--designed specifically for Distribution line inspections--was recently tested successfully in the US.
 
The Kinectrics LineVue™ device for Distribution inspections  offers many new features including: reduced dimensions and weight (~40 lbs. for new unit vs ~70 lbs. for the transmission model), a more robust welded frame, fewer moving parts, improved fastening components, and a camera to view outer conductor condition.
 
 

LineVue - Specifications 

  • Non-destructive inspection method applicable for both Transmission & Distribution lines
  • Remote controlled and easy-to-use in the field
  • Weight – 70 lb. F / Tug transports sensing head at about 75 ft./minute
  • Two sensing channels:
        • Loss of Metallic Area (LMA) – Measures average of the remaining cross-sectional area of all steel core wires over 2-3 ft. length. LMA measurement offers more than +/- 5% accuracy.
        • Local Fault (LF) – indicator which detects local faults such as severe pitting or broken steel wires over 1 inch.

Why measure remaining steel cross section?

Zinc galvanizing on steel strands of ACSR (Aluminum Conductor Steel Reinforced) and ACSS (Aluminum Conductor Self-Supporting) conductors delays deterioration of the base metal, although zinc does not contribute to the mechanical strength. Even after zinc galvanizing has been compromised, the tensile strength of steel wires (and conductors) remains close to rated strength for many years.

LineVue measures the remaining steel core cross-section to provide a direct assessment of the most important conductor parameter—actual remaining strength.
