### 額定電壓時的短路電流

${\displaystyle I_{S))$是電壓在${\displaystyle V_{S))$時的短路電流
${\displaystyle I_{SN))$是電壓在額定電壓${\displaystyle V}$時的短路電流
${\displaystyle I_{SN}=I_{S}\times {\frac {V}{V_{S))))$

### 短路功率因素

${\displaystyle W_{S))$是短路時的總輸入功率
${\displaystyle V_{SL))$是短路時的輸入線電壓
${\displaystyle I_{SL))$是短路時的輸入線電流
${\displaystyle cos\phi _{S))$是短路時的功率因素
${\displaystyle cos\phi _{S}={\frac {W_{S))((\sqrt {3)){V_{SL)){I_{SL))))}$[12]

### 漏感抗

${\displaystyle Z_{01))$是短路時，參考定子的短路阻抗
${\displaystyle X_{01))$是短路時，參考定子的單相漏感抗
${\displaystyle Z_{01}={\frac {\text{short circuit voltage per phase)){\text{short circuit current))}={\frac {V_{S)){I_{S))))$

${\displaystyle W_{cu))$ 是總銅損
${\displaystyle W_{c))$ 是總鐵損

${\displaystyle W_{cu}=W_{S}-W_{c))$
${\displaystyle W_{cu}={3}\times ((I_{S))^{2}{R_{01))))$

${\displaystyle R_{01}={\frac {W_{cu)){3{I_{S))^{2))))$

${\displaystyle X_{01}={\sqrt ((Z_{01))^{2}-{R_{01}^{2))))}$
