Convert 800kvar to kw?
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
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.
How to convert from kV into kW?
Multiply by Amps.
How do convert KVA to KW?
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
1 12hp motor takes what kva?
12HP is approximately 10.8 KVA. You would want to use a 15KVA transformer to supply this motor. KW = HP * .75 KVA = KW * 1.2 (These formulas are approximate)
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.
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.
Convert 5.0KW to KVA?
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
What should be the rating of the transformer in KVA to cater to 55KW motor?
To determine the transformer rating in KVA for a 55 kW motor, you can use the formula: KVA = KW / Power Factor. Assuming a typical power factor of 0.8 for motors, the calculation would be KVA = 55 kW / 0.8 = 68.75 KVA. It's advisable to round up, so a transformer rated at 75 KVA would be appropriate to ensure adequate capacity.
What is 360kw in kva?
To convert kilowatts (kW) to kilovolt-amperes (kVA), you can use the formula kVA = kW / power factor. If we assume a typical power factor of 0.8, 360 kW would be approximately 450 kVA (360 kW / 0.8 = 450 kVA). If the power factor is different, you would need to adjust the calculation accordingly.
Why transformer are rated in kVA instead of KW?
Transformers are rated in VA or kVA. That is because the voltage is limited by the power loss in the magnetic core, and the current is limited by the power loss in the resistance of the windings. The rated voltage times the rated current gives the transformer's rating in kVA.
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.
