If the load is single equipment, calculating the capacity of the generator or transformer is fairly straight forward. If the load is mix of various several different equipment it would be more complicated to arrive at transformer / Generator capacity. Complexity increases if you have to estimate some future unknown loads.
The rating of the generator or transformer should be such that it is loaded optimally, average being say 80 to 95 %. Since maximum efficiency of generator or transformer generally occur at these range. Also this ensures that it is not overloaded continuously and there is room for occasional short time full load too. You need to check the data sheet of the transformer or generator for more correct information.
One need to know the maximum load or peak load, average load and diversity factor and load factor. These values drive the decision on the rating of the transformer or Generator.

∙ 13y agoA transformer is going to have a kva rating on the nameplate. Divide this number by the voltage of the primary or secondary and you get the amp capacity of the primary or secondary respectively.
Do not use the voltage of the primary to determine the amp capacity of the secondary, or vice versa.

Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What are three requirement for connecting the transformer in paralle?
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
What is the maximum value power capacity of dry type transformer?
What's the maximum value power capacity of dry type
What is the oil capacity of a transformer?
Depends on the transformer. This can range from a few gallons to thousands of gallons.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What are three requirement for connecting the transformer in paralle?

What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
What is the maximum capacity of power transformer at 220kV voltage?
800 MVA
What is the maximum value power capacity of dry type transformer?
What's the maximum value power capacity of dry type
How can you find a real transformer?
Go to photograph if you see a transformer
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
When 2 power transformers are operated in parallel what would be the net capacity Is it less than the total capacity of above transformer?
iT is above Transformer because The Two power Transformers are operaTed iT for The same shape buT cuT in half
How do you claculate the secondary load of a step up transformer?
Any continuous load shouldn't exceed the rated capacity of the transformer, expressed in volt amperes.
