Corona Inception Voltage Calculator

Estimate the corona inception voltage using Peek's empirical relation.

Formula:
\[ V_{ci} = 2110\, m_0\, \delta\, r \ln\left(\frac{D}{r}\right) \]
(with \(r\) and \(D\) in meters, result in kV)

* Enter the conductor radius, spacing, air density factor, and surface condition factor.

Step 1: Enter Parameters

Conductor Radius, \( r \) (m):

Example: 0.01 m (1 cm)

Conductor Spacing, \( D \) (m):

Example: 0.1 m (10 cm)

Air Density Factor, \( \delta \):

Typically 1 under standard conditions.

Surface Condition Factor, \( m_0 \):

Typically 1 for smooth conductors.
