Perhitungan Impedansi pada saluran udara Tegangan Menengah (SUTM)

  1. Impedansi urutan positif

Dimana:

q = Luas penampang (mm2)

I =  Arus yang mengalir pada penghantar (A)

L = Panjang Penghantar (m)

∆V = drop tegangan (volt)

ϒ = daya hantar penghantar (ohm/m)

R = Resistansi penghantar (ohm)

µ0= konstatnta medan magnet 4∏x 10-4 H/km

ῲ = 2∏.f

f= frekuensi (hz)

r = jari-jari penghantar (mm)

d = geometric mean distance = jarak + r
