  • expert consultancy 
  • detailed video evidence
  • 50-megapixel images

Our solutions

We offer a range of solutions to suit your needs:

Thermal Surveys

  • We can determine if there is a thermal contrast in similar components – this can often be the precursor to equipment failure.
  • We identify high resistance joints before joint failure.
  • We uncover conductor problems, hot tower footings and earth wire continuity issues.
  • We highlight transformer, switchgear and bus bar problems where components show dissimilar hotspots (or cold spots where equipment has failed)

High Definition Condition Assessments

  • We provide detailed condition assessment of towers, fittings and ancillary equipment including all spacers, conductors, insulators, joints, repairs, bonds, shoes, hangers, bolts, washers, split pins, and earth wire fittings.
  • We can produce high definition photography of steelwork that emphasise areas in need of painting and/or steelwork repair.
  • High definition condition assessment of overhead gantries and substation equipment.
  • Different surveys to monitor overhead lines and substations, including High Definition Condition Assessments and Thermal Survey techniques.
  • The results of both types of surveys are available to you through high definition imagery and summary reports.
