The image contains two diagrams of electrical transformers with winding connections. **Top Diagram:** - It features a three-winding transformer with two triangular arrangements and one horizontal winding. - Each side of the triangle has coils labeled as: - T-1 (connected to terminals X-1 and X-2) - T-2 (connected to terminals X-2 and X-3) - T-3 (connected to terminals X-3 and X-1) - There are additional windings: - T-4 (connected to terminals X-4 and X-3) - T-5 (connected to terminals X-4 and X-1) **Bottom Diagram:** - It shows a simpler triangular winding configuration. - Each triangle side has the following coils: - T-1 (connected to terminals H-1 and H-2) - T-2 (connected to terminals H-2 and H-3) - T-3 (connected to terminals H-3 and H-1) - The outer connections are labeled as H-4. These diagrams illustrate different transformer connections used in electrical systems to enhance phase and voltage management.

Expert Solution
Step 1

The line current on the high voltage side is √3 times the phase current on the high voltage side which is 1A because the winding on high voltage side are connected in delta.

J: Thus, the line current on high voltage side is:
