![]() To calculate the amperage rating of a device from the kVA rating, just enter the value of apparent power in kVA, voltage in volts, select power supply system ( single phase or three phase) and hit the “Calculate” button to the get the result of current in A, kA, mA and MA. Similarly given the power in each phase you could easily find the phase currents. kilovolt amperes or kVA) into current “I” in amperes “A”, kiloamperes “kA”, milliamperes “mA “and megaampere “MA”. phase 1 apparent power 80 x 230 18,400 VA 18.4 kVA. The following kVA to Amps conversion calculator will convert the apparent power “S” (i.e. Conversion with Line to Neutral Voltage (VL-N).Conversion with Line to Line Voltage (VL-L).kVA to Amps Conversion Formulas & Equations Input the requested data below for each field to calculate the 3-phase or 1.You can click through to FastQuote, our online quotation tool, to select a cable that meets your size and specification requirements. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. In the formula, KVA is apparent power in kilovolt-ampere (KVA), V is the rated voltage of the transformer and I is the rated current of the transformer. Example: If an AC has 22kW power and its power factor of 0. ![]() kW to kVA conversion formula: kVA kw / PF. To convert you need to divide the kw value with its power factor value. ![]() The cable size results for International standard cable are calculated from IEC 6: Low Voltage Electrical Installations, selection and erection of electrical equipment – Wiring systems and are based on 230V and 415V voltage drop. How to convert kW to kVA The conversion of kW to kva is very simple. Primary Current (current on High Voltage side) is 5.25 amps. This figure is a constant found in three phase, as the phases do not generate the same amount of power (simultaneously). You can learn more about this particular example from the 3-phase motor amperage calculator. Example: Primary Voltages or High Voltages (H.V) is 11000 volts. Businesses that require three-phase power need to add an extra component in the formula to arrive at the correct transformer size, i.e., square root of 3 (3) or 1.732. It covers Low Voltage armoured AWA and SWA cables, insulated cables including twin & earth and 6491X, and insulated and sheathed cables in both PVC and LSZH such as H07ZZ-F and SY cable. Done The three-phase calculator shows you the values of other parameters: Phase current 5 A Line voltage 400 V Phase angle 33 deg Power factor 0.84 Apparent power 5.96 kVA and Reactive power 3.24 kvar. The results for British standard cable are calculated from BS7671 (18th Edition) Requirements for Electrical Installation, IEE Wiring Regulations, and are based on 230V and 415V voltage drop. ![]() ![]() Complete the sections below to calculate your results. Voltage (root-mean-squared) x Amps (root-mean-squared) x Power Factor (PF) (a three-phase circuit would multiply. Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. Some Useful Conversion Factors and Formulas. ![]()
