Can a delta-delta system with standard displacement be phased with another delta-delta system with alternate displacement?

In a delta-delta system, the phase relationships and the manner in which the coils are connected determine the ability to phase the systems together. When one delta-delta system is designed with standard displacement, it typically means that the phases are arranged in a specific order. In contrast, a system with alternate displacement has a different phase arrangement, usually resulting in a shift in the phase angles.

For two delta-delta systems to be phased together effectively, they must have compatible phase relationships. If one system has standard displacement and the other has alternate displacement, the phase angles will not align correctly, leading to potential issues such as circulating currents or even equipment damage. This incompatibility ensures that the systems cannot be operated together without significant risk.

Therefore, the correct response highlights that phasing a delta-delta system with standard displacement together with another delta-delta system using alternate displacement is not feasible under normal circumstances, as their fundamental phase relationships are divergent.
