Dear friends,
It reads in my text - "Assume that a generator is rated at 600V, 120 kVA. This means that it is capable of supplying I = 120 kVA/600V = 200A."
I have a few questions about this statement:
#1 Does it mean that the generator can provide an open-circuit sinusoidal voltage such as v(t) = 600√2 cos(2∏ft)? If it does, why don't we need to specify the value of frequency?
#2 Is '120kVA' obtained under the assumption that the gnerator will generate 120kVA/600V=200A current from a voltage source of 600V? But since we don't know what kind of load is going to be connected to the generator, how can we be sure what current value it will supply?
Thank you!
