Mobile computing applications at Entergy

Summary form only given as follows. This presentation outlines the use of mobile computing to automate field inspections and maintenance. At Entergy, the mobile computing project entered the planning phase in the mid-90´s to target three areas: transmission line maintenance, vegetation management and substation maintenance. The hardware and software requirements of each of these areas are discussed. There are two distinct hardware platforms in use with customized templates for each area of application. Using a GPS system, the present location of the field device in relation to the asset (transmission line structure or substation) can be determined. The presentation traces the evolution of the interface between the field device and the host computer that enables data upload. The substation application has an additional capability of tracking workflow that assists in the determination of actual time needed to complete specific maintenance tasks and in time entry. The presentation concludes with the impact of mobile computing on Entergy´s maintenance program.
