Three-Phase “T-Connected” Overhead Distribution Transformers

The Power Partners “T-Connected”, overhead distribution transformer can be used to serve most three phase applications up to 500kVA. “T-Connected” transformers consist of two single-phase core/coil assemblies. This type of connection is also referred to as a “Scott-T” connection.

“T-Connected”, overhead distribution transformers can be used to serve most three-phase applications. However, triplex designed three phase transformers are needed for some applications where large motors are load and these motors are frequently started. Oil field pumping loads and some irrigation pumping loads should use only the triplex designs.
