One interesting configuration for a three-phase bank is theopen delta connectionused extensively in rural distribution systems. The open delta connection uses two single-phase transformers. An open Y-∆ connection requires only two phases plus the neutral on the primary side of the bank in order...
banks, using reactors in one with delta connection with phase switches and the other in star connection with line switches, has been presented [26] with the ability to reduce its line current THD through cancellation of certain low-order harmonics without using phase-shifting transformers or ...
