Which of the following is not a disadvantage of a Swinburne’s test?(

1.	Which of the following is not a disadvantage of a Swinburne’s test?(a) The stray-load losses can’t be determined by this test(b) Steady temperature rise can’t be determined(c) Does not give results about satisfactory commutation(d) Machine gets damagedThe question was asked during an interview.This key question is from Swinburne’s Test in chapter Efficiency and Testing of DC Machines
Answer» CORRECT CHOICE is (d) Machine gets damaged To elaborate: For increasing life and durability of a machine we CARRY out such tests. But STRAY load LOSSES, steady temperature rise is not determined by this method. Also, results about satisfactory commutation are not given by this method.
