Abstract
What is BS 7450 - Economic optimization of power cable size about?
BS 7450 is a British Standard that deals solely with the economic choice of conductor size based on joule losses. Voltage dependent losses have not been considered. Likewise, matters such as maintenance, energy losses in forced cooling systems and time of day energy costs have not been included in BS 7450 . An example of the application of the method to a hypothetical supply system is given in BS 7450 . Note 1: It is recommended that the method given in BS 7450 should not be used for cables operating on system voltages equal to or greater than the following (see IEC 287) Note 2: Modifications to the method given in BS 7450 to take dielectric losses into account are under consideration.
