The relation between the old and new per unit impedance values is given by: |
| A. | \(Z_{pu}^{new} = Z_{pu}^{old}\frac{{S_B^{old}}}{{S_B^{new}}}{\left( {\frac{{V_B^{old}}}{{V_B^{new}}}} \right)^2}\) |
| B. | \(Z_{pu}^{new} = Z_{pu}^{old}\frac{{S_B^{new}}}{{S_B^{old}}}{\left( {\frac{{V_B^{old}}}{{V_B^{new}}}} \right)^2}\) |
| C. | \(Z_{pu}^{new} = Z_{pu}^{old}\frac{{S_B^{new}}}{{S_B^{old}}}{\left( {\frac{{V_B^{new}}}{{V_B^{old}}}} \right)^2}\) |
| D. | \(z_{pu}^{old} = Z_{pu}^{new}\frac{{S_B^{new}}}{{S_B^{old}}}{\left( {\frac{{V_B^{old}}}{{V_B^{new}}}} \right)^2}\) |
| Answer» C. \(Z_{pu}^{new} = Z_{pu}^{old}\frac{{S_B^{new}}}{{S_B^{old}}}{\left( {\frac{{V_B^{new}}}{{V_B^{old}}}} \right)^2}\) | |
