Has anybody here done any  residual IT product calculations?
Thanks in advance.

Yeah, what Keith said.

RE: Residual IT product Calcualtion

I am trying to calculate the telephone inteference on Utility side since we are adding a variable frequency drive to the system. The utility transformer is 3MVA 25KV/4.16KV, VFD is 2200hp. This is the only load at this facility.  I calculated the balanced IT product is 7500. But ETAP does not have the ability to do the residual IT calculation. So I am trying to do it by hand. Any idea how to calculate it?
