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'.

∙ 13y agoThe amperage would be dependant on the voltage of the transformer's secondary. KVA is Amps x Volts x 1000.

What size of 12v transformer will run 600watts?
Amps * Volts = Watts Amps * 12 = 600 600/12 = Amps = 50 amps You would need a reserve capacity, so I'd go somewhere between 60 or 100 Amp rated transformer. Transformers are rated in volt-amps which is usually calculated the same as watts. But the term "watts" technically does not apply to transformers. So you need a 600 volt-amp transformer or, as Redbeard has suggested, you need an 800 or 1000 volt-amp transformer. That's a lot of amps for a 12 volt system so I recommend you double check your requirements. You will need a #2 gauge wire if your requirements are correct.
A stepup transformer has 100 turns on the primary coil and 500 turns on the secondary coil If the primary voltage is 120 volts what will be the secondary voltage?
A step-up transformer has 100 turns on the primary coil and 500 turns on the secondary coil. If there is 120 volts and 10 amps on the primary, what will be the current in the secondary? 2 amps.600v 2A
How many amps can be put on a 125 amp service?
You should not load a 125 amp panel any more than 100 amps.
How many amp do you need to run a house?
Minimal 100. Depends on load draw of home. Can be 200 amps or 400 amps as well.
How many kw does it take to make 100 amps?
If the 100 amps is powered by 10 volts, you have 1 kw, or 1000 watts. watts = volts X current The 'k' simply means kilo, or thousand.
100 amps mccb trip when charged it is connected to small power transformer?
what is the fault in the transformer, it trips when it is charged.it is charged through the 100 amps MCCB.
What wire size to carry 16 amps 100 ft?
14
How many amps 10-3 carry at 100 ft?
Typical residential rated current for 10 AWG is 30 amps. The 100 ft. Increases resistance which will cause a small voltage drop, but this isn't an issue here.
What will be output current for 30KVA Isolation Transformer?
who knows 30kva means 30000 volts per ampere so if the output is 100 volts the amps will be 300 amps so do the math.

What is the capacity 0f 100 KVA electric transformer?
KVA means thousands (K) of volts (V) times Amperes (A). A 100 KVA transformer can deliver 1000 amps at 100 volts or 500 amps at 200 volts etc.
Can you use 20 kva transformer in a home?
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
How many amps come into a home from the main?
max. 100 amps then fuse blows.
How many amps does it takes to light up a led 100 watt?
You need the volts times the amps to equal 100 Watts. On 12 v that is 8.33 amps, or on 200 v is it 0.5 amps.
How many amp in 480 vac 3- phase primary transformer if the secondary it's 120 vac?
This 480-v three-phase transformer probably has a 208-v three-phase secondary which has 120 v from each line to neutral. In that case the primary current is 0.433 times as much as the secondary current, so 100 amps in the secondary means 43.3 amps in the primary.
How many amps 3 pH 2 hp 240 v draw?
100 amps
How many ampere in 240 volt with 100 watts bulb?
Current (amps) = power (watts) / voltage = 100/240 = 0.42 amps
