Enter the sag (in) and the line voltage (volts) into the Calculator. The calculator will evaluate the Conductor Distance. 

Conductor Distance Formula

CD = SQRT(S) + V/150


  • CD is the Conductor Distance (in)
  • S is the sag (in)
  • V is the line voltage (volts)

To calculate the Conductor Distance, divide the line voltage by 150, then add the square root of the sag to the result.

How to Calculate Conductor Distance?

The following steps outline how to calculate the Conductor Distance.

  1. First, determine the sag (in). 
  2. Next, determine the line voltage (volts). 
  3. Next, gather the formula from above = CD = SQRT(S) + V/150.
  4. Finally, calculate the Conductor Distance.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

sag (in) = 1.7

line voltage (volts) = 12
