The zero sequence reactance of transmission line is always larger than the positive sequence reactance. Is that right? Why? Thank you very much

1. For a transformer, when one side of the three-phase transformer is connected into a triangle or a star with ungrounded neutral point, the zero sequence reactance of the transformer is always infinite from this side, because no matter how the other side is connected, when zero sequence voltage is applied on this side, zero sequence current cannot be sent into the transformer



Which God can give you the centralized parameters of transmission lines in 10kV distribution network, mainly the values of positive sequence resistance and inductance, and zero sequence resistance and inductance


Different specifications and lengths of line conductors lead to different parameters. It depends on the specific line. There will be no unified parameters
