Overhear Conductor
Overhear Conductor
(OP)
I had asked t local utility provide me with SC MV so I can design the substation ground grid. They have given me the Sc for the TS, instead on customer location. The conductor is 565KCMIL at 44KV AL.
I never heard of this type of conductor. I also know that the distance and the way conductors are placed makes a difference in impedance values. I really appreciate if I can get any feedback on this issue.
Thanks

RE: Overhear Conductor
I only have the size,length and type of conductor (AL)
conductor mounting height, spacing, size GMR, circuit configuration are probably the same fo all 44KV circuits( I can find that)
Size GMR?
What refernce I can use to calculate the impedance with this information?Whats the formula?
Thank you

See ftp://ftp.areva-td.com/NPAG/Chap5-46-77.pdf
or http:/
for the whole manual which is a handy reference.

I have 150mm spacing between 44KV vertical configuration system.
I can not find X,R which I need to calculate Z1 and Z0.
I have heard that there is a manual from" Aluminum conductor association???" which has all the info, but I don have it.
