English: $Z_{pu,\ new} = \ Z_{pu,\ old}*\ \frac{(KV)_{B,old\ right}^{2}}{(MVA)_{B,\ old}}*\frac{(MVA)_{B,\ new}}{(KV)_{B,new}^{2}}$ Therefore this $Z_{B,\ old} = \ \frac{(KV)_{B,old\ }^{2}}{(MVA)_{B,\ old}}$ right.
Telugu: $Z_{pu,\ new} = \ Z_{pu,\ old}*\ \frac{(KV)_{B,old\కుడి}^{2}}{(MVA)_{B,\old}}*\frac{(MVA)_{B,\new}}{(KV)_{B,\{2}}$ అందువల్ల ఈ $Z_{B,\ పాత} = \frac{(KV)_{B,పాత} =^{2}}{(MVA)_{B,\ old}}}
