A: They are both the same the first is the product volts times amperes the second is related to volts and amperes also. The difference is the second term is used to rate Transformers power output in terms of voltage to amperes. Example a 1kva means that you can expect 1kv at 1 ampere on the transformer output . But here is the trick the transformer only put out 250 volts So now what It means is 250v at 4 amperes nothing has changed the power remains the same 1 kw

To convert KW to KVA just leave the power factor (pf) out of the equation.

Formula for Kilowatts = I x E x pf/1000.

Formula for KVA = I x E /100.

How do we Calculate Kwh to Kvah?

To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.


How many kva is 21000 kw?

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.


Convert 800kvar to kw?

The same way, as you convert Appels to Carrots ........... There is a formula: KVAr = KVA / KW or cos=KW/KVA &gt; Yes, we are treating KW, KVA, &amp; KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse


Which is to consider in sizing generator kva or kw ratins?

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


Convert kw single phase to 3 phase kva?

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.

How do you calculate DG set current from kva?

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.


How calculate kvar?

kvar can be calculated as follows the a product KVA andt the sine of the angle between the KVA and KW.


How do you calculate kilovoltamps when kilowatts is known?

To calculate kilovolt-amps (kVA) when kilowatts (kW) is known, you can use the formula: kVA = kW / power factor. The power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit.


What is the kw of 100kva transformer and how you calculate?

The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.


37 kilowatta equals how many kVA?

kva and kw are related as KVA = (KW/PF) pf:power factor

How do you change ac tonnage to kva and kw?

To convert AC tonnage to kVA and kW, use the following formulas: For kVA: kVA = (tonnage x 3.517) For kW: kW = (tonnage x 3.517 x power factor). Remember to consider the power factor of the system when converting from tonnage to kVA and kW.

How do you calculate power factor kvr?

Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.


Convert 2KW to KVA in single phase?

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.
