GMR of Bundled Conductors Calculator
Calculate the effective Geometric Mean Radius (GMR) of bundled conductors.
For a 2-conductor bundle: \[ \text{GMR} = \sqrt{r \times D} \] For a 3-conductor bundle (equilateral triangle): \[ \text{GMR} = \left(r \times D^2\right)^{\frac{1}{3}} \]
Step 1: Enter Bundle Parameters
Example: 0.01 m (1 cm)
For 2-conductor: center-to-center distance; for 3-conductor (equilateral), spacing between any two conductors.
Example: 100 m
