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.
Show solution of conversion of 1KVA to watts.?
1kva means 1kv per ampere therefore 1 amp flowing and 1 kv deduce to be the product of the two or 1kw
How do you compute ampere if the given is kvA kW power factor and voltage?
Some confusion hereKW and KVA are units of power. The ampere is a unit of current. If you divide power by the voltage involved, you can determine the current involved, in amps. Power (watts) = volts x ampsA volt-amp is a watt. (A volt times an amp is a watt.)I=(KVA*1000)/(1.732*V) (Three Phase)AMP=KW/1000*V*PF--------------------------------------------------------------------------------------------------------------KW or KVA can be converted to one another but you cannot convert them to amps. You can compute amps by using this formula,KW = I x V x 1.732 x P.F/1000 (Three phase)KVA = I x V x 1.732/1000 (Three phase)
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.
37 kilowatta equals how many kVA?
kva and kw are related as KVA = (KW/PF) pf:power factor
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 > Yes, we are treating KW, KVA, & KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse
How do you calculate power factor kvr?
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
How calculate kvar if p is 560 kw and kva is 700?
The formula is that kW^2 + kVAR^2 equals kVA^2 or if you prefer, the kW and the kVAR are the two sides of a right angled triangle and the kVA is the hypotenuse. So here you have a 3-4-5 triangle times 140, in other words 420-560-700, and the kVAR is 420.
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 amp for gen set 120 KVA output 415 Volt?
i try ......gen set 120 KVA and output 415 Volt 1 KVA = 0.8KW so 120 x 0.8 = 96 kW A = w/v ~ A = 96000/415 = 231.3 Amp I' it right ? If wrong give correction
