GMR of Two-Layer ACSR Calculator
Calculate the effective Geometric Mean Radius (GMR) of a two-layer ACSR conductor.
Using the formula:
\[
\text{GMR}_{\text{eff}} = \left( \text{GMR}_{\text{steel}}^{n_s} \times R_{\text{alu}}^{n_a} \right)^{\frac{1}{n_s+n_a}}
\]
where:
\( \text{GMR}_{\text{steel}} \) is the steel core GMR,
\( R_{\text{alu}} \) is the effective radius for the aluminum layer,
\( n_s \) is the number of steel core elements, and
\( n_a \) is the number of aluminum strands.
* Enter values in meters for radii and the counts for elements.
