Discussion on “comparison of calculated and measured corona loss curves” (Peek), New York, February 17, 1915. (see proceedings for February, 1915)

J. B. Whitehead. Mr. Peek states that in the case of clean wires his losses would begin at the voltage E
v
, rising abruptly from 0 to the values shown for their voltages on the curves. As I understand it this voltage E
v
is that at which corona breaks out on clean wires and is calculated from the now well known expression involving the diameter of the wire and the distance between wires.
