Hydro-Québec and MIR Innovation have developed a highly accurate transmission line analysis system.

Introduction

A subsidiary of the Canadian state-owned power generation, transportation and marketing giant Hydro-Québec - MIR Innovation (abbreviation MIR: maintenance, control and robotics), has developed a drone adapted for the joint work with a special sensor called "Linecore".

Linecore is a special sensor developed by the company for the implementation of high-precision analysis of the condition of high-voltage wires. The developer said that power lines are constantly exposed to aggressive environmental influences and thus wears out a lot. Previously, the company spent a lot of money, effort and time on identifying and analyzing emergency sections of controlled power lines, now, thanks to a specially developed tandem "Drone - Linecore", inspection has become easier, faster, more reliable, safer and more accurate, and costs have been reduced significantly.

About the product

The work of the tandem can be carried out both with the participation of a person and autonomously. When the system is installed on a power line, it can work around the clock 24 hours, since the drone is recharged from the high-voltage wire on which it operates. The drone can also go home on its own if weather conditions do not allow for safe further inspection.

LineCore - can determine the state of galvanic protection of power lines, as well as the state of the core and each core. Determines the zinc layer thickness of the entire section with amazing accuracy, anomalies caused by corrosion, minimizing the costly sampling process. LineCore is the ideal tool for obtaining detailed information on the condition of aluminum steel wires (ACSR).

The data obtained from LineCore can then be used to calculate wire degradation to estimate residual life.

Advantages

  • Continuity of operation: does not require violation of the integrity of the line for sampling and shutdown of transmission lines in operation.
  • Ease of Use: Easy to use software for calibration, verification, archiving and analysis.
  • Versatility: Works with any type of ACSR wire.
  • Built-in LineROVer: able to pass any obstacles in the form of grounding wires, splicing sleeves.
  • Built-in LineScout: is able to overcome obstacles in the form of protruding bundles, single wires and any other similar obstacles.
  • Durability: Designed for use in aggressive environments.
