Problem 2(40) It is necessary to supply a 10 load with a rated voltage of 240V in an industrial facility from a 30 , 2,000 KVA Delta-Wye connected transformer with voltage transformation ratio of 34.5 kV/600 V, and a 25 kVA single-phase transformer with a voltage transformation ratio of 230 /115 V 30 Transformer 34.5 kV 600 V 30 Transformer 16 Transformer reconnected as an Autotransformer 10 Load 2,000 KVA 34.5 kv 7600 vi 1-Y Note: This is not the detailed connection diagram requested in (a) 10 Transformer 25 KVA 230/115V H1 X1 10 Load Von=240V 00000, H2 X2 a) Show how windings of conventional transformer must be connected to operate as an autotransformer (AT) to supply power from 30 transformer to load, taking into account that load must operate at rated voltage (+/-5%). Elaborate a detailed connection diagram that shows connection of autotransformer to three-phase transformer and single-phase laod. b) What's the maximum apparent power that autotransformer may deliver to the load? Smax AT= KVA c) Show voltage across AT windings and current flowing through AT windings when it delivers its rated capacity to load. Also show load voltage and current. Report only magnitudes of voltages and currents.
