1kw=1.25kva
by this relation 75kva=60kw
p=1.732*380*I*1
I=60000/1.732*380*1
I=91Amps
CommentPower factor is irrelevant to this question. You don't need to convert the kV.A rating to kilowatts, simply divide 75 000 V.A by (1.732 x 380). The answer is 114 A.
This, of course, assumes that the question refers to a three-phase generator and that 380 V is the line voltage.

∙ 12y agoOn the 208v side: 208 amps
On the 480v side: 90 amps
Transformers are generally used from higher voltage to lower voltage but they can be used in either direction.

How many output amps is a 75 KVA generator?
It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps
How do you calculate the output voltage of a transformer if kva rating is known?
You can't determine the output voltage of a transformer by knowing kva. Transformers will be marked as to input and output voltages. Some will have multiple input and output voltages. The output voltage depends on the ratio of coil turns between input and output.
How many output amps is a 75 kva transformer?
For single phase, KVA = (line to ground) * (phase current). A 75kVA 480 to 208Y/120 volt transformer is a fairly common transformer. I assume this is the type of transformer you are referring to. 75k / 120 = 625 Amps. As an FYI, the 208Y voltage is the line to line voltage, which is equal to (phase 1) - (phase 2), where the phases are separated by 120 degrees, thus (phase 1) * 1.732 For three phase, kVA = (line to line voltage) * (phase current) *(sqrt 3), 75k / 208 / 1.732 = 208 Amps.
How do you convert Amps to KVA for a single phase system?
use 1.0 as your PF Understand that K=1000, so KVA simply means thousands of volts times amps. First, multiply KVA by 1000 to get VA, then divide by the voltage of the system to get amps. Example: 6KVA, 240V single-phase. 6 * 1000 = 6000 VA 6000 / 240 = 25A
How many amps will a 750kva electrical transfromer carry?
It depends on the incoming primary voltage. For a 5kva utility transformer receiving 15,000 volts on the primary the current drawn would be one third of one amp to give you an output of 5,000 VA (watts). Just remember this, volts x amps = watts or volt amps.
How many output amps is a 75 KVA generator single phase?
The formula you are looking for is , A = kva x 1000/Volts.
How many output amps is a 75 KVA generator?
It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps
Can you use a step up transformer 110220 with output of 16 kva?
Yes, but your input current is going to be high at 133 amps. The output of the transformer is not going to be 16 KVA, that is the rating of the transformer.
How many output amps is a 45 kva transformer?
There is not enough information provided to answer. KVA is short for "Kilo Volt Amperes". That is, thousands of Volt Amps. In order to determine how many Amperes are flowing, you must know at what voltage it is operating. Amperes = 45,000 ÷ volts Bill Slugg
How many output amps from a 75kva transformer fed with 480 ckt.?
It depends on what the output voltage is. You only specified the input voltage, not the output voltage. The equation is 75 Kva = {some} amps times {some} kilovolts. (Minus incidental losses, of course, but you still need to know output volts.)
How many kva on 88.88 amps in 1phase secondary 230 volts?
20.44 kva
How do you calculate the output voltage of a transformer if kva rating is known?
You can't determine the output voltage of a transformer by knowing kva. Transformers will be marked as to input and output voltages. Some will have multiple input and output voltages. The output voltage depends on the ratio of coil turns between input and output.
500kva how many amps given capacity?
500 KVA how many amps? almost 650 Amps according to formula.
45 kva at 208 120 volts amp load?
I am assuming that you are talking single phase. 45 kva is k = 1000, v = volts, a = amps. 45 kva is 45000 volt / amps. Input 45000 divided by 208 volts = 216 amps. Output 45000 divided by 120 volts = 375 amps. There are other losses in the transformer but as a general rule of thumb this is the calculation that you would use.
How many amps will a 240 volt single phase 15 kva generator supply?
62.5 amps
How many amps is a 5.5kva generator good for?
4.6605 kva
How many KVA is 62 amps?
At what voltage? When you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
