The output of a generator is 440 v at 20 a. it is to be transmitted on a line with resistance of 0.60 ω. to what voltage must the generator output be stepped up with a transformer if the power loss in transmission is not to exceed 0.010% of the original power?

The voltage of the generator is 7.27 kV.

Explanation:

Given that,

Output of generator = 440 V

Current = 20 A

Resistance = 0.60 Ω

Power loss =0.010%

We need to calculate the total power of the generator

Using formula of power

Where, V = voltage

I = current

Put the value into the formula

Th power lost on the transmission lines

The current passing through the transmission line

We need to calculate the voltage of the generator

Using formula of voltage

Put the value into the formula

Hence, The voltage of the generator is 7.27 kV.
