the positive, zero impedance of acsr 330mcm line

the positive, zero impedance of acsr 330mcm line

the positive, zero impedance of acsr 330mcm line

(OP)
Could you tell me the value of the positive and zero impedance of the ACSR 330MCM line which has two conducts in  one phase?
Thanh you very much for your reply.

RE: the positive, zero impedance of acsr 330mcm line

To determine the sequence impedances several parameters are required in addition to the size of the cable such as geometric configuration of the line, type of cable, ground wire, transposition, ground resistivity, etc.

In general, the positive and negative impedances are the same and the zero sequence could be more than 3 times larger than the positive or negative sequence impedance.

RE: the positive, zero impedance of acsr 330mcm line

Ditto what cuky2000 said.  You also need to know the stranding (steel and aluminum).  Are you sure it is 330 MCM?  This is non-standard; it's probably 336.4 kcmil (MCM).
