Capacitance of 3Ph Line with more than One Circuit

       Consider the arrangement of conductors shown in the Fig. 1.
Fig. 1

       The voltage between phases a and b is given by,
      We have,  Vab + Vac = 3 Van

           qa + qb + qc = 0
...         qb + qc = - qa
       Capacitance per phase will be nothing but 2 Can
