The surge impedance of a typical overhead transmission line is approximately in the range of:

A400 to 500 ohms
B10 to 20 ohms
C1000 to 2000 ohms
D40 to 50 ohms

Explanation

The surge impedance Z_c = sqrt(L/C) for overhead lines is typically between 400 and 500 ohms due to large conductor spacing.
