The zero sequence inductance can be calculated using L0 = V0open/I0short where V0open is the open-circuit voltage for the zero sequence and I0short is the short-circuit current for the zero sequence.
- Open-Circuit Voltage for Zero Sequence: you'll need to perform a simulation or measurement under zero sequence conditions. You can apply a zero sequence voltage at the motor terminals while keeping the other phases open-circuited. Measure the resulting voltage across the motor terminals.
- Short-Circuit Current for Zero Sequence: Similarly, you'll need to simulate or measure the short-circuit current under zero sequence conditions. This involves applying a short circuit to the motor terminals while injecting a zero sequence current. Measure the resulting current.
Hope this helps
