What the size of transformer & Generator when I calculate Electrical Load?
Answer:
You must define the type of load, whether reactive, resistive, or a combination of both. A resistive load can be calculated from the product of current, and voltage, but a reactive load has to take in to consideration the power factor (so called wattless power) of the device, so you would have to consult an electrical engineer to perform the calculations.
please make ur question mpore clear. same generator can deliver different loads according to the requirements.. so there is no size dependent on load..
I'm not sure I completely understand what it is you want to know - the question isn't really clear. However I do know that whatever it is you're trying to calculate, if you don't know the answer to your question you shouldn't be doing the calculation. Get a qualified electrical engineer.
Transformers and generators are both rated in KVA,
so power factor is not an issue if you use this unit
for the calculation.
Transformers are generally sized at 125% of diversified load.
For generators, the same except that the largest
motor that will start must be considered at 200% of
its rated current.
These are very general rules and may vary with the situation.
Some Codes have other required minimum sizes.
Consult a professional.
