The three-phase impedance load shown in Figure 8.7 has the following phase impedance matrix:

\[Z_{\mathrm{p}}=\left[\begin{array}{ccc}(6+j 10) & 0 & 0 \\0 & (6+j 10) & 0 \\0 & 0 & (6+j 10)\end{array}\right] \Omega\]

Determine the sequence impedance matrix \(Z_{\mathrm{s}}\) for this load. Is the load symmetrical?
