# Negative sequence admittance (or impedance)

Hi

Do you know how can I add negative sequence impedance (or admittance) for transmission line? Transformer? Generator? And load?

When I open each of them Branch, I can only see positive sequence and zero sequence, I can see where I can add the negative sequence impedance?

In transformer, I can only see the positive sequence impedance and I'm adding the zero sequence admittance to (X01), but I don't know where to add the negative sequence admittance?

In generator, I can't find where I can add the X2 values?

Thank you for your help in advance!
