Objectives
To develop an ACSR Conductor Corrosion detection piece of equipment. Production of a functional specification System Specification Development of Technology Technology Validation
Abstract
Conductor life and reliability are of increasing importance as 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 overhead line (OHL) 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. The existing equipment is obsolete and increasingly difficult to operate and maintain.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. Development National Grid and Hydro Quebec are working in collaboration to establish an updated version of the ACSR condition assessment probe. During 2011/12 we have joined forces to understand the theory behind the technology and began work on a working prototype. The method that has been proposed for this project includes; Stage 1: Functional Specification Stage 2: System Specification and Detailed Project Plan Stage 3: Options for commercial arrangements Stage 4: Development of Technology Stage 5: Technology Validation Stage 6: OptioneeringNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
