Transformers with “V” - connection


Transformers with the "V" connection are used wherever there is a need for single-phase power supply with high power output. Standard supply procedure of such receivers from the three-phase network causes a strong asymmetry and loads only two phases. Using transformers with the V connection significantly decreases the asymmetry of network load.
