3 Phase Motor Wiring Diagram Star Delta

Three-phase Transformer Connections (Wiring Diagrams Included)
Aug 29, 2021And in delta connection, phase voltage and line voltage are the same and line current is √3 times phase current. In close delta-delta condition, Now, in open delta condition, one transformer is removed. Therefore, the line current I 2B is equal to the rated secondary current of a transformer. In open delta condition,

3-phase 380 V to 3-phase 230 V - Electrical Engineering Stack
Nov 03, 2018\$\begingroup\$ If you have 3-phase 380 V in delta configuration, you have also 3-phase 220 V in star configuration requiring an additional neutral connector. But if you want 230 V, you need 400 V. Of course you may use 3 phase power transformer, primary in delta, secondary in star. It will be portable for very low power. \$\endgroup\$ –[PDF]
