Objectives To prove that electromagnetic phased array technology could be utilised to detect cables with a low magnetic signal, to enable progression to a further development phase. Documented tests conducted in a replicated field environment proving that the technology can detect and quantify the type of cable buried.
Abstract There is a significant risk of fatal or severe injury as a result of a cable strike when excavating in the highway. This is a major hazard for all utilities and specifically Gas Distribution Networks due to the frequency in which there is a requirement to access pipes in a built up environment. A critical step in the safe system of work for excavating in the highway is the detecting, identifying and marking of services. A key part of this is the utilisation of an avoidance tool by a competent person. This is a mandatory requirement in NGGD procedure and HSG47 (third edition). The existing services present in the ground may contain live power cables that have been capped off (called stubs/pot ends), cables may be live but not transmitting a magnetic signal or may be so well balanced that they cannot be detected by existing tools. Therefore, there is a need to develop a technology that is capable of detecting such cables with a high level of accuracy. A feasibility study will be undertaken that will: ; investigate a detector methodology based on a phased array Electromagnetic sensor configuration; investigate a detector based on pulsed Electromagnetic sensorConsisting of two aspects: ; Modelling potential arrangements and selecting the most suitable for building a laboratory test version, and;; Create the laboratory test setupNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
