There are "inverse V connection," as well as "Scott connection," "V connection," and "staggered connection."
In three-phase transformers, there are various connection methods, among which we introduce the special connection known as "special connection transformer." Starting with the "reverse V connection," which allows for a single-phase output circuit from three-phase input, there are also "Scott connection," "V connection," and "zigzag connection," which enable two single-phase output circuits. 【Features】 ■ Reverse V connection: Allows for a single-phase output circuit from three-phase input. ■ Scott connection: Allows for two single-phase output circuits from three-phase input. ■ V connection: A connection method used when obtaining three-phase from two single-phase transformers. ■ Zigzag connection: Mainly used for grounding transformers, allowing for arbitrary phase changes based on the number of winding divisions. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 ■ Reverse V Connection - The capacity is the voltage on the single-phase side multiplied by the current. - Since the V phase on the input side carries twice the current of the U and W phases, attention is needed for input capacity and wiring materials. ■ Scott Connection - The capacity is the voltage on the single-phase side multiplied by the current multiplied by 2. - By connecting loads of the same capacity to each of the two output circuits, the input current of the transformer becomes equal, achieving balance in the three-phase power supply. ■ V Connection - Up to 86.6% of the total capacity of two transformers can be used. ■ Zigzag Connection - Due to the ability to change the phase arbitrarily, it is sometimes used for rectification purposes. *For more details, please refer to the PDF document or feel free to contact us.
