There is an interconnector which is a transmission line used to t4ransfer large amounts of power from one section to another part of the system.. Short circuit test has been carried out and the question asks the effect of introducing resistance into the interconnector? How could we minimse the effect of this resistance when transferring bulk power between the generator and the consumer?

Second question is on three phase power transformer.. we were asked to calculate short circuit impedance and resistance and then we found short circuit reactance by using this equation: Z^2=X^2+R^2

and then we are given that the nominal rating of the transformer is 3kVa at 400 V line to line. Whats the percentage reactance? Assuming this iis star configuration, how would we solve this question?

Thank you in advance friends.
