Calculation of cross section when conductor length is known [t-head3]
The minimum cross section is calculated for the know maximum use of the network.
| l |
=
|
Length of conductor in m |
| Smin |
=
|
minimum cross section in mm2 |
| ρcu |
=
|
specific resistance of copper, when nothing else given 0,018 Ωmm2/m |
Note
When the result of the calculation doesn´t give a normal cross section use the next highest normal cross section.
Calculation of conductor length when the cross section is known [t-head3-col]
For a known conductor cross section the maximum conductor length is calculated.
| lmax |
=
|
Length of conductor in m |
| S |
=
|
Conductor cross section in mm2 |
| ρcu |
=
|
specific resistance of copper, when nothing else given 0,018 Ωmm2/m |
