k is 1000
V is volts
A is amps
basic algebra kVA = (V * A)/1000
120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
1 VA (VOLT AMPERE)= 1 WATT
1 k(1000) VA = 1000 watts
a 100 watt light bulb would use 1 KVA hours in 10 hours.
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
A kva load in the text that you use it is the same as a wattage load. To find your answer just total up all of your appliance wattage's, portable and hard wired, in the unit and this will give you an idea of what you have for a load.
Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.
For normal power factors (pf=80%), you have 0.8 kW for every kva. In general however, kW = pf x kVA. Where pf is the power factor, it is the cosine of the angular difference between the voltage and the current of a circuit in alternating current circuits.
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
KVA is a measure of power, while amp (or ampere) is a measure of current. KVA meanes kiloVoltAmps. 1 kVA = 1000 V*A. so 225 KVA = 225,000 VA (volts * amperes) So you would need to also know the voltage, in order to find the amperes.
i donot know
S= (1/1000) UI √3Where S in kVA; U in V; I in A; hence I= 1000S/ (U √3)
1.035 KVA
min: 0.5 KVA MAX: 1.5 KVA
kva and kw are related as KVA = (KW/PF) pf:power factor
The values you state are two different values. KVA is the value of voltage times amperage times 1000. The voltage value of 240 volts is just 240 volts. If you have an amperage it can be applied to the first equation to find the KVA value.
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
635kva
To convert horsepower (hp) to kilovolt-amperes (kVA), you can use the formula kVA = hp x 0.746. Therefore, for a 12hp motor, the kVA rating would be approximately 8.95 kVA.
KVa is not the same as the amperes because KVa is the unit for reactive power while amperes is the unit for current.
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.
