How do you calculate KWH by KW and Running Hours?
You multiply the power by time, ie kW*h
Which formula is used to calculate kW from HP?
what formula is used for calculate flow rate of pump vs kw
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)
How do you calculate the electricity bill per month for a house?
By how many KW Hours you use
What size transformer is needed if you have 30 amps of 480 volts?
watts = amps x volts400amps x 480V = 192,000 watts192,000/1000 = 192KWYou would need 192KW generator at 277/480 The formula for kilowatts is, kW = I x E x 1.73 x pf/1000. kW = 400 x 480 x 1.73 .90 = 298944/1000 = 298.9 or 300 kW generator.
Which fuse is used for 100kva transformer?
1o amper
What is the maximum current of 2500kva transformer?
You need to know the Primary and secondary voltages to do the calculation. we only have 100Kva transformers on our salt furnaces as an example: 100000va / 12v = 8333 amps the secondaries , wire, and electrodes are water cooled.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
How mach load is used 100kva transformer?
i will try my best to answer this quistion, but u must not mind if i make a mistake! >>> the rating of an elctrical machine depend upon the loses in it. if, there are any losses in the machine due to power factor than the machine will b rated in KW and if there is no loss due to power factor than the machine is rated in KVA. so there are no losses in a transformer due to power factor so it is rated in KVA. as the KW= KVA* power factor so, kVA= KW/power factor here, KVA=100 so, KW= 100*power factor u can derive from here that the load on a transformer depends upon the power factor. as the power is always less than unity so the load will be less than 100KW. thankyou!
Why transformer rating is not given in kw?
Transformer rating is based on the maximum temperature a transformer can run at. This temperature is dictated by the amount of current flowing through the transformer windings. This is why transformers are rated in KVA (voltage * current), not kW - it doesn't matter what the phase relationship is between voltage and current, just the magnitude of the current.
Why alternators are measured in Kva but not in KW?
Depending upon the connected load ( R, RL, RC or RLC) with a transformer, the power goes ou from a transformer may be of two types: 1. Active Power; measured in kW 2. Reactive Power; measured in kVAR If the rating will be in kW, then kVAR rating would not be accounted but if the rating is in kVA then it is possible for us to calculate the total active and reactive current as well as the powers, at a particular system voltage!
How many kilo watts in 10kv?
at first point you should determine the also the secondary voltage of the transformer, secondly you should explain what is the application of this transformer. if you want a special transformer, it is you to decide how much power is needed to be transferred via transformer, and designer tells you it is economical or not. by the way, if i want to refer you to a standard close to your application, following sizes are available for a 20kv/400v transformer: 50kVA,100kVA, 150, 200,315,500,630,800,1200,1600,2000,2500 and 3500kVA i hope this helps you
How do you calculate crane motor ED?
How to calculate motor kw for cranes
How do you calculate condenser capacity?
condenser capacity(kw) = compressor cooling capacity (kw) + compressor input (kw) power condenser capacity(kw) = Pf + Pa
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
How do you calculate KWH by KW and Running Hours?
You multiply the power by time, ie kW*h
How many amps can a 100 KVA transformer carry?
A 100kVA transformer is rated for...100kVA. That is its' power rating, and it is based off the current that is flowing through the transformer (the I^2*R losses are the limiting factor). This can be 80kW and 60 kVARs, or 100kW and 0 kVARs, or 100kVARs, or anywhere inbetween.Another AnswerThe 'power' rating of a transformer is the product of its secondary voltage and its secondary current, expressed in volt amperes or multiples thereof. It's not expressed in watts, because to know the 'true power' of the transformer, the manufacturer will need to know the power factor of the load, and that could vary considerably. Incidentally, the symbol for kilovolt ampere is 'kV.A', not 'kVa'.
