Three-Phase Transformer Connections | Electrical Engineering
The service transformer used for interconnection can have a great influence on the impact that Distributed Generation will have on the power quality. The advantages and disadvantages of the common three-phase transformer connections are: 1. Grounded Wye-Wye Connection: It is favored because of its reduced susceptibility to ferroresonance on cable-fed loads and fewer operating restrictions when being switched for maintenance. [...]
