Description
This is the resistance of the external wiring calculated from user
entries of wire length and wire gauge:
Rseries = [Resistance per Foot] * Wire Length
Resistance Per Foot is calculated from the table below: The first
column is Wire Gauge (AWG); the second column is Resistance
per Foot.
4 AWG (0.2043 in, 5.189 mm) → 0.0002485 Ω/foot
6 AWG (0.1620 in, 4.115 mm) → 0.0003951 Ω/foot
8 AWG (0.1285 in, 3.264 mm) → 0.0006282 Ω/foot
10 AWG (0.1019 in, 2.588 mm) → 0.0009989 Ω/foot
12 AWG (0.0808 in, 2.053 mm) → 0.001588 Ω/foot
14 AWG (0.0641 in, 1.628 mm) → 0.002525 Ω/foot
16 AWG (0.0508 in, 1.291 mm) → 0.004016 Ω/foot
Wire Gauge (AWG)
: selects the wire gauge of conductors
between the PV string and the point at
which the I-V curve is being measured.
Wire Length (Feet, one-way)
: enter the wire length in feet.
For instance, if you have two 10 foot
leads running between the I-V unit and
the string, enter ―10‖ (not ―20‖).
