where

 D = distance between conductors

 r = radius of conductors

 δ = air density correction factor

 p = pressure in Hg

 t = temperature in ⁰C

 V_c = corona inception or critical disruptive voltage

 V_p = rms phase to neutral operating voltage

 m₀ = surface irregularity or stranding factor

 g₀ = breakdown strength of air = 21.2 kV/cm

 f = frequency
