SRD calculations have been made to cover the range in unit values set out
above. Sample results are shown in Figure 4.15 . As shown in the figure, a range
in SRD is provided, reflecting the various combinations in unit values given
above. The lower bounds are likely to be applicable to the minimum resistances
