Q2. a) Discuss the circumstances where parallel operation of transformers may be considered beneficial. b) Two three-phase transformers have the following secondary equivalent circuit parameters per phase where the values have been derived from your student number using the same method as in Question 1: x=2 y=8 Transformer 1: Transformer 2 R = 0.03X 0 R2 = 0.04Y 0 X, = 0.09X X2 0.12Y0 For example: If your student number is c1700123, then R, = 0.032 n and R, = 0.043 0. Calculate the current delivered by each transformer if the load draws a current of 200 A at a power factor of 0.8X lagging when connected in parallel. State any assumptions which you make. For example: If your student number is c1700123, the power factor is 0.82 lagging.

b)
Two three-phase transformers have the following secondary equivalent circuit
parameters per phase where the values have been derived from your student
number using the same method as in Question 1:
X=2 y=8
Transformer 1:
R = 0.03X 0
Transformer 2
R2 = 0.04Y 0
X, = 0.09X N
X2 = 0.12Y 0
