KVA is the unit for the apparent power i.e it's the vector sum of the true power in KW and the reactive power in reactive volt-amperage. So, to get the value of the KVA for the 30KW,just divide the active power(30kw) with the power factor of that load.
KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.
the unit of generators power is KVA becoze the kva is the power that contain the active power (KW) and the reactive power mean that the name plate of any generator must contain the rated kva of it (like the transformer P (KW) = P (kva) * cos fi P (KW) = V I cos fi for single phase P (KVA) = V I when cos fi closed to 1 this will increase the useful power that exit from the generator or transformer with my pleasure
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
70 kVA stands for 70 kilovolt-amperes, which is a unit used to measure electrical power. It represents the apparent power in an electrical system, combining both the active (real) power and the reactive power.
The power in watts equals the VA times the power factor. For a resistive load like a convector heater or an iron the power factor is 1 For other things like motors the power factor might be 0.7. A poor power factor is not a good thing because more current is needed from the supply to produce a given amount of power, so that requires thicker wires (more expensive). For a power factor of 1, 70 kVA = 70 kW For a power factor of 0.7, 70 kVA = 50 kW.
To convert 2 kW to kVA in single phase, you need to know the power factor. If we assume a power factor of 0.8 (common for many single-phase loads), the conversion formula is kVA = kW / power factor. Therefore, for 2 kW at a power factor of 0.8, the result would be 2 kVA / 0.8 = 2.5 kVA.
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
Formulas you need for single phase calculations. KVA = I x E/1000, KW = I x E x pf (where pf = power factor). For your question multiply the KVA by the power factor to get KW and then move the decimal point three places to the right to get watts. They are virtually the same. A watt is volts times amps. KVA is thousand of volts time amps. KVA and KW ratings are the same.
There are ~5.9 kVA with 5600 watts and a power factor of 0.95. power factor is defined as the real power (watts) divided by the complex power (volt amperes): .95 = 5600/VA VA = 5600/.95 = 5894.7VA = 5.89kVA
KVA is the unit for the apparent power i.e it's the vector sum of the true power in KW and the reactive power in reactive volt-amperage. So, to get the value of the KVA for the 30KW,just divide the active power(30kw) with the power factor of that load.
KVa is not the same as the amperes because KVa is the unit for reactive power while amperes is the unit for current.
It depends on the power factor, which depends on the reactance of the load.For a typical power factor of 0.92, 150 KVAR translates to 383 KVA, which translates to 352 KW.Power factor is the cosine of the phase angle (theta) between voltage and current. KVA times cosine (theta) is KW, while KVA times sine (theta) is KVAR.
It could be as much as 63 kW (63,000 Watts) into a load with a power factor of 1.0. For other loads, multiply the kVA by the power factor.
Power = volts x amperes x power factor. However, VA or kVA is simply the product of volts x amperes, and does not take into account the power factor. Note that in many practical situations, the power factor is close to 1.
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
