Calculation of AC resistance of flexible conductor
With this tool the AC resistance of a flexible wire can be calculated for two temperatures. It let’s you determine the input parameters for the calculation of the current carrying capacity, following Cigre601 and IEEE-738 methods. The calculation is based on the formula’s in IEC 61597, which is also often used by suppliers in their datasheets.
