Bundled Conductors GMR Calculator
Calculate the effective Geometric Mean Radius (GMR) for bundled conductors.
For a single conductor, \(GMR = 0.7788\,r\). For an \(N\)-conductor bundle (with \(N>1\)) arranged in a line with equal spacing \(d\),
\[
GMR = \Bigl(0.7788\,r\,d^{(N-1)}\Bigr)^{\frac{1}{N}}
\]
* Enter the conductor radius (m) and, for bundles, the spacing (m) and bundle size.
