In case of unity Power factor

  • One Watt is = 1 Volt - Amp (from the formula P = I x E),
  • One kilo Watt is a kilo Volt Amp.
  • 1 kW = 1 kVA

For PF = 0.8, 1 kVA = 0.8 kW

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



How do you convert 1.5kva to watts?

KVA·PF = KW 1.5 KVA x 0.8 PF = KW 1.2 KVA = KW 0.0012 KVA = W


How many KW is in 150 KVA?

120 KW @ 0.8 Power factor


How do you calculate transformer KVA if kw is given?

Usually transformers are rated in kVA but if kW is specified, the kVA must be assumed to be the same. The kVA often exceed the kW but it cannot be assumed in this case.


How many kva is 120 kw?

If the power factor is 0.8 it's 150 kVA.



How many BTU is 5 KW?

The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU


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




1 kva is equal to how many watt?

If the power factor is 1, i.e. a resistive load, the 1 KVA is 1 KW. If the power factor is less than 1, i.e. a reactive load, then multiply PF by KVA to get KW. For example, if PF is 0.92 and KVA is 1, then KW is 0.92.


How many kva is 7000watt?

7000 watts is 7 kW. To find the kVA, divide by the power factor, which is always 1 or less, so the kVA number is always either equal to or more than the kW.



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.


6000VA Inverter is how many kw?

KVA=KW*Power factor, considering PF 0.9, 6KVA=KW*0.9 KW=6/.9=6.67


Why transformer are rated in kVA instead of KW?

KW is multiplication of KVA and power factor. Power factor is load dependent and varies as per the type of load. Hence the rating or capacity is mentioned in KVA not in KW


How do you change ac tonnage to kva and kw?

1 tone = 1540 Watts=1.540 KW. whereas 1 KW=1.25 KVA. I think you have got the answer.


How many kw equal to 250 kva?

200kw is equal to 250kva


What is the diffrence between KVAR and KVA?

KVAR is reactive power only; KVA is the vector sum of KVAR and KW KVA^2 = KVAR^2 + KW^2


How do we Calculate Kwh to Kvah?

we can calculate kwh,kva,kvah by following formulas kva=[(kw)2 + (kvah)2]1/2 kw=[(kvah)2- (kva)2]1/2 kvah=[(kva)2-(kw)2]1/2


How many kw equals 1 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.


How do you convert kw to kva?

kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.


What difference between kva and kvar?

KVA = KW + jKVAR KVA is full power, which includes the real power component (watts, or kW), and the reactive component (VARs, or kVAR).
