KVA is very simple, it is the Volts x Amps of an AC circuit in units of 1000. For a single phase AC circuit VA = E x I. KVA = (ExI)/1000 So if you have 120 VAC and 15 A then: VA = 120 x 15 = 1800; KVA = 1800/1000 = 1.8 For 3 phase circuits we need to add the square of 3 (= 1.732) as a factor. VA = 1.732 x E x I and KVA = (1.732 x E x I)/1000 So if you have 480 VAC and 23 A then: VA = 1.732 x 480 x 23 = 19,121; KVA = 19,121/1000 = 19.1 Note that KVA is higher than KW (true power) in circuits that are not purely resistive. The vector difference of the two is "Power factor".
1 HP = 0.9325 kVA 1 KVA = 1/0.9325 HP
To convert amps to kVA, you use the following formula: Amps = (kVA x 1000 / voltage) / 1.73
KVA is a rating for complex power (real + reactive power): KVA = KVAR + KW Also, there is 1000KVA in 1MVA, so there's at least 1000KVA in 1MW, but if the reactive power load is very high, there may be substantially more KVA.
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
The formula is that kW^2 + kVAR^2 equals kVA^2 or if you prefer, the kW and the kVAR are the two sides of a right angled triangle and the kVA is the hypotenuse. So here you have a 3-4-5 triangle times 140, in other words 420-560-700, and the kVAR is 420.
1 HP = 0.9325 kVA 1 KVA = 1/0.9325 HP
The formula you are looking for is , A = kva x 1000/Volts.
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
The formula to find amps is: I = (KVA x 1000)/(E x 1.73) I = (2500 x 1000) / (480 x 1.73) I = 2500000 / 830.4 I = 3010.597A
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
To convert amps to kVA, you use the following formula: Amps = (kVA x 1000 / voltage) / 1.73
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
The same way, as you convert Appels to Carrots ........... There is a formula: KVAr = KVA / KW or cos=KW/KVA > Yes, we are treating KW, KVA, & KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse
kV is kilovolts, kW is kilowatts, kVA is kilovolt amps and kVAR is kilovolt-amps reactive. A common formula is kVA-squared = kW-squared + kVAR-squared.
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
The formula you are looking for is volts x amps divided by 1000.
The term horsepower has several definitions, depending on usage. According to WikiPedia, the Electric Motor usage is 746 watts. One kva (kilo-volt-amp) is 1,000 watts, so you might be able to say that one kva is 746,000 watts. Unfortunately, kva depends on phase angle and, except for a power factor of one (purely resistive), kva is not the same as kw (kilo-watts). Someone else with more knowledge than I will need to enhance this answer.
