This chapter will examine both the key scheme design management procedure and a number of other major design-related procedures. The scheme design management procedure will apply to virtually all schemes, where as many of the others will only be used as and when the scheme requires. In summary, the procedures examined will comprise the following (NB: The titles used are typical but may vary from company to company): 1. Design management 2. Protection and control settings management 3.Thermal rating schedules 4.Protection and automatic reclose/switching schedules 5.Equipment nomenclature 6.Operation diagrams 7.SCADA systems management 8.Drawings management.
