Two-Layer ACSR GMR Calculator
Calculate the effective Geometric Mean Radius (GMR) for a two-layer ACSR conductor bundle.
For a single conductor, \(GMR = 0.7788\,r\). For a bundle with one inner conductor and \(n\) outer strands,
\[
GMR = \Bigl(0.7788\,r\,R^n\Bigr)^{\frac{1}{n+1}}
\]
* Enter the conductor radius (m), the number of outer strands, and (if applicable) the outer strand spacing (m).
Step 1: Enter Parameters
Example: 0.01 m
Example: 6 (for a typical 7-strand ACSR)
Distance from inner conductor center to outer strand centers
