Conductor life and reliability are of increasing importance as Aluminium Conductor Steel Reinforced (ACSR) conductor reaches the end of its technical asset life. Conductor condition information is vital when making optimised asset replacement decisions. Approximately 20 years ago, the CEGB developed non destructive test equipment to measure steel core loss. The equipment developed from this project is still in use and is the only proven method of detecting loss of galvanising in ACSR conductors. The existing equipment is obsolete and increasingly difficult to operate and maintain. The analysis software runs only on legacy hardware and with unsupported DOS software only. There is no modern equivalent equipment available world-wide.
