Definition of Commutating and Through-Fault Impedance?
Definition of Commutating and Through-Fault Impedance?
(OP)
I'm looking at a customer spec that asks for a specific Commutating Impedance and Through-fault Impedance. It is for a 12 pulse transformer-rectifier application. I think commutating impedance would be the leakage inductance and copper losses in the transformer. I would imagine through-fault impedance would be the same. They are asking for a 6.5% commutating and 4% through-fault impedance. I have no information about what is feeding me so I can't add any source impedance to the calculation if neccesary.
Any insight would be helpful.
Regards,
Jim
