Is it single-phase or 3-phase transformer? Also indicate load at which regulation is to be determined?
Hi, The transformer is 3 phase "An 11kv to 415v...."Load for regulation ? Nothing has been omitted from the original question this is all i have. As a load has not been specified i assume the load is the combined resistances of the winding and leakage reactance. Thats my understanding of the question, what do you think ?
Here is answer. Regulation is calculated for rated load.word fileKindly rate the answer. BONUS will be appreciated.
Thanks for your help. To be honest i have calculated an entirely differently way and was unable to follow your workings. The good news is i get the same answer so your reply has still helped. Here are my workings.
Let me know what you think.
There are two ways to calculate regulation.1) per unit method2) Conventional method.Per unit method is straight and chances of committing mistake are rare, In this method, we should know how resistance and reactance are converted in per unit values. Also it avoids the type of connection, that is, whether it is delta or star connected. Conventional method is lengthy and chances of committing mistake are quite high. That's why I rarely use this method. In this method, we have to use actual values of current etc.
Don't you see that you also have used per unit method?
Not really if i am honest , just happy with an answer, its the last question in a long assignment thats been all maths without much practcal application behind it
Thanks for reply
Now i have to rate you again and pay you a further £11 for an explanation to an answer you have already been paid for ?
I appreciate your help and reckon i paid a fair price for it. May even need your help again at some point and if i do i will pay a fair price again for it
