Final answer:
The connections between the windings of a three-phase transformer cannot be easily changed to accommodate different systems.
Step-by-step explanation:
The statement that the connections between the windings of a three-phase transformer can easily be changed to accommodate whatever system the transformer is used on is false.
The connections between the windings of a transformer are fixed and cannot be changed without physically rewiring the transformer. These connections are determined during the manufacturing process according to the intended use and voltage requirements of the transformer.
Changing the connections in a three-phase transformer would require significant modifications to the internal wiring and is not a simple or practical task.
