negative G and B values

[Paul Simonns]

Hello all,

Why sometimes the G and B values of the y matrix are negative?

Shouldn't they all be postive?

Thanks

[Roger Dugan]

No. They can be + or - .

Negative B is quite common. Negative G might be unusual, but that's how the math works, especially for some 3-phase models.

Calculate Y by hand. You'll see.

Thanks Roger!
