A grading can be said ideal if total group that made at beam in is maximal and each group has access (only can access) to k, with connection:
æ N ö = N!
è k ø k ! (N – k) !
Where:
Line connection = k
Total line out = N, and N > k ® there is interconnection
Example:
N = 4
k = 2
Total maximal group that must be made:
= æ 4 ö = 4! = 4.3 = 6 group
è 2 ø 2 ! (4 – 2) ! 2
The figure as follows:
So the problem, from (total group) x k = 6 x 2 = 12 line out ® interconnecting so that be 4 line out.
æ N ö = N!
è k ø k ! (N – k) !
Where:
Line connection = k
Total line out = N, and N > k ® there is interconnection
Example:
N = 4
k = 2
Total maximal group that must be made:
= æ 4 ö = 4! = 4.3 = 6 group
è 2 ø 2 ! (4 – 2) ! 2
The figure as follows:
Figure 5.13 configurations for ideal grading.
So the problem, from (total group) x k = 6 x 2 = 12 line out ® interconnecting so that be 4 line out.
