Hello friends
I tried the exercise as mentioned in the question below. It is mispelled int he question as 23 ohms total resistance. Please correct it as 23 Ohms total reactance (I presume so).
I tried to get the voltage regulation of transformer using following formula based on engineering book.
Vr = Full load current (Total resistance * Cos Pi + Total reactance * Sin Pi) / Volatage in primary
Cos pi is 0.8
Sine Pi is 0.6
Total resistance = R1 +R2(V1/V2)
Total reactance = 23 ohms as given in the question.
Iam getting percentage regulation of 0.55 % as per the formula, but the textbook answere says as 3.06 %. I do not know how they derived this as steps are not given. Can anybody help me the steps.
Thanks and regards
