ElectraNet is the private owner, manager and operator of the South Australian high-voltage electricity transmission network. ElectraNet’s current aerial inspection and patrol capability involves a helicopter hovering at each tower whilst an on-board inspector visually identifies insulator condition issues and records any identified problems with a hand-held digital camera. This process is time consuming, expensive and does not capture asset condition historical data.
In 2012 Nova Systems was engaged by Electranet to complete an aerial services feasibility study to address these issues. Nova Systems worked with ElectraNet to understand the current aerial inspection and patrol capacities. Using this knowledge, Nova Systems developed a set of high level business requirements to define the requirements of the inspection, and an Aerial Services plan to detail how to develop the capability. A short period later, Nova Systems was again engaged to develop a Business case as recommended in the Aerial Services plan. This document proposed a fully costed solution, for the life of the technical solution and included a detailed risk analysis.
In 2014, Nova Systems was again engaged by ElectraNet to undertake a detailed feasibility study on the currently available aerial service technology that is cost effective with the potential to reduce the inspection time. Nova Systems adopted a systems engineering approach to the problem in an industry where systems engineering is not often practised; to ensure that the end solution will in fact meet the clients need. Nova Systems repeat engagement with ElectraNet is testimony to the high quality work Nova Systems provides for its clients.
