Solidly bonded cable impedance matrix

The capacitance matrix looks similar to the impedance matrix in Table 3.3a-2. The capacitance between the core and sheath of the homogeneous model is identical to that of the solidly bonded cable. The equivalent capacitance Q4 of the cross-bonded cable in Table 3.3b-2 is given as the sum of the elements as shown in Equations 3.44 and 3.45. 

Figure 3.9 shows a sequence current measurement circuit for a solidly bonded cable. The following equations are given from the 6x6 impedance matrix in (3.47) and Figure 3.9 ... 

In Table 3.3a-l, the upper 3x3 matrix expresses three-phase core impedance [ZJ, the right upper and the left lower matrices are three-phase core to sheath [ZJ and sheath to core impedance [Z J = [ZJ and the lower 3x3 matrix is three-phase sheath impedances [ZJ. The upper line is the resistance [Q/km] and the lower one is the inductance [mH/km]. The [ZJ matrix of the solidly bonded cable in Table 3.3a-l is the same as that of fhe cross-bonded cable in Table 3.3b-l. The impedance in the last column,...
