Unformatted text preview: V srated 7200 volt = and we found previously: Z eqhs 16.53 132.3j + ( ) = e. Find the voltage regulation of the transformer if it is delivering rated current at a rated voltage and a power factor of 1.0. Solution : First we must find rated current I srated S rated V srated = I srated 1.389 10 3 amp = The actual current is at a power factor of 1.0, so the angle is: acos 1 ( ) = 0deg = and the current is: I s I srated cos ( 29 I srated sin ( 29 j -= I s 1.389 10 3 amp = The actual secondary voltage is: V s 7200 volt =...
