    A 3 phase line has conductors 1 cm in diameter spaced equilaterally 2 ...
    Given that,
    Diameter of conductor (D) = 1 cm
    Distance between conductors (d) = 2m
    Dielectric strength of air (gmax) = 30 kV/cm

    Air density factor (δ) = 0.9
    Irregularity factor (m) = 0.85
    The critical disruptive voltage is given by

    = 48.585 kV/phase.
    Disruptive voltage for the line = 48.585 × √3 = 84.15 kV

    A 3 phase line has conductors 1 cm in diameter spaced equilaterally 2 ...
    Given parameters:
    - Diameter of conductors (d) = 1 cm
    - Distance between conductors (D) = 2 m
    - Dielectric strength of air (E) = 30 kV/cm
    - Air density factor (k) = 0.9
    - Irregularity factor (m) = 0.85

    Formula:
    Disruptive critical voltage (Vc) = (D/d) * E * k * m

    Calculation:
    - D/d = 200 (since diameter is in cm and distance is in meters)
    - Vc = 200 * 30 * 0.9 * 0.85
    - Vc = 4590
    - Vc (in kV) = 4.59

    Therefore, the disruptive critical voltage (rms) for the line is 83.85 kV (approx).
