A single phase transformer of (k) transformation ratio is to be used as a step-up autotransformer. If the kVA capacity is increased by 50%, find: 1. The transformation ratio of the origin transformer (k), and the new transformer ratio of the autotransformer. 2. The currents in different parts of the autotransformer windings related to the currents of the original transformer. 3. The inductively and conductively transferred kVA related to the kVA of the origin transformer.
