Project Description Optimal Grid

Predictive Maintenance of Overhead Transmission and Distribution Lines Optimal Grid provides a comprehensive mobile solution for non-destructive assessment of utility wooden poles and engineering load calculation. The solution addresses a challenging problem of finding substandard poles in the utility or telecommunication network.

To manage assets across the grid effectively, the solution provides a combination of hardware and software applications that produce health indicators including remaining strength and probability of failure for in-service wooden poles.

The hardware device uses a series of sensors that allow creation of pole tomography. The software application takes into consideration all relevant factors specified in engineering standards including regional historical extreme wind data and environmental parameters.

The detailed information captured throughout the inspection process is utilised to generate specific reports based on customer needs and perform various types of data analytics.


  • Inspect wooden poles using sensor based non-destructive technologies.
  • Design replacement pole onsite by considering regional and environmental factors in order to maintain reliability of overhead line.
  • Calculate all transient and dead loads on the poles and assess probability of failure of the pole.
  • Conform to engineering ANSI and individual country standards.
  • Find remaining strength, breaking strength, probability of failure and predictive time to failure for the pole.
  • Optimise maintenance of assets by prioritising pole replacements.
  • Perform valuation analysis based on objective pole condition data.
  • Perform advanced data analytics to find correlations between parameters and performance of various pole species and loading conditions.
  • Build a long term pole replacement strategy.
