WebVolt-amperes are useful only in the context of alternating current (AC) circuits. This tool converts volt-ampere to btu per hour (va to btu/h) and vice versa. 1 volt-ampere ≈ 3.4121 btu per hour. The user must fill one of the two fields and the conversion will become automatically. 1 volt-ampere = 3.4121 btu per hour Formula volt-ampere in ... WebAC current is calculated by the power factor of 0.86 for single-phase supply and 0.8 for three-phase supply. Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase …

WebSingle phase amps to kVA calculation formula The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000: S(kVA) = I(A) × V(V) / 1000 3 phase amps to kVA calculation formula Calculation with line to line voltage WebDec 12, 2014 · Dec 8, 2014. #3. I think the question you are trying to ask can be answered in this way. Take 15,000 VA, divide it by 208 volts, and divide it again by 1.732 (i.e., the square root of 3). The result is 125 amps. We are allowed to go up to 125% of that value, which brings us to 156 amps. So I would select a 150 amp panel. phlebotomist yearly pay
What does 40VA rating for transformer mean?
WebI(A) = 1,800 VA 120 V I(A) = 15 A So, a circuit with 1,800 volt-amps of apparent power at 120 volts has a current rating of 15 amps. You can use our amps to volt-amps calculator to reverse this conversion. How to Convert Volt-amps to Amps for Three-Phase Circuits WebI(Primary) = Primary current in Amps I(secondary) = Secondary current in Amps V(primary) = Primary Voltage in Volts V(secondary) = Secondary Voltage in Volts Transformer current calculations: Transformer turns ratio, V(primary) * I(Primary) = V(secondary) * I(secondary) Web150 VA Power Transformers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 150 VA Power Transformers. t statistic 5%
