APPLICATION OF COMPUTER IN CABLE SIZE SELECTION FOR SPECIFIC LOADS

Abstract

A good Engineering Services Design must specify appropriate cable type and standard cable sizes for the designed Electrical Loads.tn Electrical Engineering profession the problem of use of appropriate cable-types, cable sizes, fuse ratings in Electrical Services in buildings involves a lot of mental resources due to intricate and tedious calculations associated with the exercise and efforts expended in scanning through volumes of Electrical Engineering books on standards and specifications. The specification of wrong cable types, SIzes and fuse ratings in buildings has contributed immensely to several Electrical circuit related hazardous fire incidence. This has over the years constituted a great deal to insecurity of life and property. This project is a Computer aided solution (Computer Program) to the problem of f recommending the right Electrical Conductors for Electrical Services with specific focus on a range of flexible cables. Chapter 1 justifies the need for the project (Application of Computer in cable size selection for specific Loads) and considers the history of information communication Chapter 2 traces the evolution of Computer generations up till the end of the 20th Century and forecasts the trend in the 21 th Century. Chapter 3 deals with system Design procedures and selects Basic language as the programme language for the project. Chapter 4 conducts an in-depth analysis of the written program. Chapter 5 comments extensively on the limitations ofthe project and makes far-reaching recommendations. Finally the programme and program outputs ofthe project are contain in the appendix. This project is therefore another success in the application of computer in making the complex Electrical Engineering duty of Load calculation for specific flexible cable types ranging from 60 0 C rubber- insulated BS 6141 to 185 C rubber- insulated BS 614 1 to 185 0 C glass fiber types very easy. The programme is however based on the 16th Edition of institution of Electrical Engineers regulations.
