D10 Energy Efficient Power Cable Selection (Datadisk)
This program calculates cable size taking account of type of cable, installation method, circuit length, overload protection, ambient temperature and circuit grouping. Results are presented for the minimum size (i.e. BS 7671) and for each incremental size up to the most economic size (i.e. IEC 1059). For each size, the overall lifetime cost and the payback period are calculated. The economic calculations take account of load growth, discount rate and increases in energy costs. Cable and installation costs can be modified by the user to suit local conditions. 1998.
D11 Busbar Design Software (Datadisk)
This program, based on the formulae found in CDA publication 22, Copper for Busbars, calculates the current rating, size and working temperature of common configurations of copper busbars. The minimum size and the savings and payback periods that accrue from the use of larger sizes, up to the most economic, are calculated. The economic calculations take account of copper price, fabrication cost, load growth, discount rate and increases in energy costs. 1998.
D12 K-Factor Calculation Software (Datadisk)
This software calculates the K-Factor of a load from the harmonic content according to US and European practice. The results can be used to select transformers or to determine suitable de-rating factors for transformers. The software requires Windows 95 or higher or NT version 4.0 or higher.
