In physics, Peek's law is a description of the conditions necessary for corona discharge between two wires:
Additional recommended knowledge
ev is the "visual critical corona voltage" or "corona inception voltage" (CIV), the voltage (in kilovolts) required to initiate a visible corona discharge between the wires.
mv is an irregularity factor to account for the condition of the wires. For smooth, polished wires, mv = 1. For roughened, dirty or weathered wires, 0.98 to 0.93, and for cables, 0.87 to 0.83.
r is the radius of the wires
S is the distance between the wires
δ is the air density factor. It is calculated by the equation:
gv is the "visual critical" potential gradient, and is calculated by the equation:
