I am Mechanical Engineer, I want to know about fundamentals of electricity

I have following questions

p=VI

If a power generated from a gas turbine is 300 megawatt, then what is the value of V & I in this power, and what when it is flowing from wire suppose 32kva, 11kva?
how can we measure the capacity of a conductor for electrical power flow

    I am afraid that there is some confusion with volts , amperes and watts.
    The VA rating of a generator gives the maximum power output from that.
    In this case 300 megawatt (300 million VA).
    Divide this by the voltage to get the amperage. Size of the cable will depend on the ampere output.
    Ample data available on the net.

    VA is actually power generated It is the reactive power generated in the generator.

    And kVA means Kilo volt ampere.

    And KW is the power consumed in the device it stands for Kilowatts

    VA infact is the total power(apparent power) generated.
    VAR is the reactive power component and
    Watts is the real power.

    VA^2 = VAR^2+W^2
