Question

Zero sequence reactance of generator is very small.why??

Answer 1

Are you asking why it should be small?

Or what reduces it?

You can reduce it by the following means:

- Applying solidly-earthed-neutral type inverter.

- Inserting star-delta connected transformer for infinitive zero sequence impedance in the source side.

- Coupled reactor with very high zero sequence impedance inserted.
