Q2. As an engineer for a private contracting company, you are required to test some dry-type transformers to ensure they are functional. The nameplates indicate that all the transformers are 1.2 kVA, 120/480 V single phase dry type. (a) With the aid of a suitable diagram, outline the tests you would conduct to determine the equivalent circuit parameters of the single-phase transformers. (6 marks) (b) The No-Load and Short Circuit tests were conducted on a transformer and the following results were obtained. No Load Test: Input Voltage 120 V, Input Power = 60 W, Input Current = 0.8 A - Short Circuit Test (high voltage side short circuited): Input Voltage = 10 V, Input Power = 30 W, Input Current = 6.0 A (6 marks) Calculate R. X. R and X eq m
