Calculate the load current from the load data available. Dear my supply has 230/380 voltage. Get Free Android App | Download Electrical Technology App Now! I want the wire thickness and heat it may produce for 500kva load at 480v . Hence the cable rating formula can be written as, Cable size = 1.5 x Full Load Current. drop is 3 percent and 5 percent. Example: Lets we calculate required cable sizing for 5.5kW/7.5HP motor which is Cable sizes are typically depicted as far as cross-sectional territory, American Wire Gauge Voltage drop Ampere/Meter which you will get from the cable supplier (in mV). spilling into uninsulated metal pieces of an apparatus, power device, or other electrical gadgets. is there any simple or shortest way for fix this problem. However, this formula does not employ a K-factor. Voltage Drop - Generally we take the percentage of voltage drop and the most common percentage of voltage or current conveying limit of a cable. conductors. Can you Please send me the furmula of 3phase and single phase for calculation of cable. Three core and earth cables have three conductors, which are shading coded, dark dim, and darker just as there are two phases - Single phase or three phase. 1. amps: 250 2. have an info voltage resilience go. We depends on ad revenue to keep creating quality content for you to learn and enjoy for free. 3 Phase 5 wire to be taken. Get the cable size corresponding to this derated current from the catalog. Hello, I need cables and wire calculations for aluminium and copper, table for diameters and Amp. and find the diameter of both. Cable (or conductor) estimating is the way toward choosing suitable sizes for electrical power cable conductors. Distance is less than 15 meter. K=90 (for Al cables), K=140 (for Cu cables). Step 3 Check / Calculate Voltage Drop: Check for voltage drop with the cable size chosen. Derating factors will be available in cable catalog. (To be on a safer side you can assume 2 times the load in kW or else you can apply the formula for power to get the exact current), Once you know how much current the cable is gonna carry you can easily finalize the rating of protection device (, For the time being you can assume the standard cable size corresponding to your. It has to be less than 15%. Hi Everyone, Kindly give me guidance for the calculation of cable size. Cable sizes are typically depicted as far as cross-sectional territory, American Wire Gauge (AWG), or kcmil, contingent upon the geographic district.
