Which connection type prefers WYE and dislikes Delta?

The connection type that prefers WYE and dislikes Delta is indeed WYE. In electrical systems, especially in three-phase power applications, the WYE configuration is often chosen for its ability to manage neutral connections effectively. This configuration allows for a neutral point where the voltages are balanced, which is particularly useful in grounding and in supplying single-phase loads.

WYE connections provide several advantages, including the ability to operate with lower phase voltage compared to the line voltage, making it safer and more practical for connecting to low-voltage equipment. It also facilitates better load balancing, helping to reduce the risk of overloading any one phase in a system.

In contrast, the Delta connection does not have a neutral point and is typically more suited to applications requiring higher starting torque, but it may not handle single-phase loads or unbalanced loads as efficiently. While Delta may be suitable for certain specific uses, it lacks some of the flexibility and safety features that WYE offers.

Additionally, transformer configurations can indeed utilize both types of connections depending on the application; however, the focus here is on the advantages of WYE connections in terms of stability and versatility in power distribution systems. Thus, WYE is clearly the more preferable choice in scenarios where these advantages are sought.
