Initially measure the width (mm). Following that, measure the thickness (mm). After that, calculate the material carrying capacity factor (amps/mm 2). Finally, use the following formula to determine the busbar current. Calculate the current carrying capability of a 150 (width) x 25 (thickness) (in mm) busbar in the copper material.
We’ll use a current density of 1.5 A/mm² for copper in this case. Using the formula, we can calculate the busbar’s current-carrying capacity. In this case, the busbar can safely carry a current of 225 A, ensuring that it can handle the required load without overheating.
A very approximate method of estimating the current carrying capacity of a copper busbar is to assume a current density of 2 A/mm2 (1250 A/in2) in still air. This method should only be used to estimate a likely size of busbar, the final size being chosen after consideration has been given to the calculation methods.
Silver busbar current Carrying capacity = 1.6 * Busbar width in mm * Thickness in mm Amps Example: Calculate the 150 x 25 mm busbar current carrying capacity in all the above materials, Silver bus bar carries 6000 Amps (1.6*150*25) Current. Enter the breadth and thickness of the busbar; do not enter the length of the busbar.
Let’s say we have a copper busbar with a width of 2 inches, a depth of 0.5 inches, a frequency of 60 Hz, a length of 24 inches, and a temperature correction factor of 1.0. Using the formula: I =3 amperes So, the current flowing through the busbar is 3 amperes. FAQs Q: What is a busbar?
Using the formula, we can calculate the busbar’s current-carrying capacity. In this case, the busbar can safely carry a current of 225 A, ensuring that it can handle the required load without overheating. 1. Why is the current-carrying capacity of a busbar important?
