three phase isolation transformer connecti
ThreePhase Transformer Connections
The three phase transformer consist three transformers either separate or combined with one core. The primary and secondary of the transformer can be independently connected either in star or delta. There are three possible connections for a 3phase transformer bank. They are deltadelta connection, starstar connection, stardelta connection and deltastar connection.

VFD to feed a 3phase isolation transformer(?)
· I am wondering if I could employ a 10HP VFD with a fixed output in place of the rotary phase converter, with a 3phase "isolation" transformer between the VFD and the loads, and be able to use the native switching that is present on the machines without destroying the VFD in short order. I'm guessing "no", but I don't know why it isn't feasible.

Three Phase Transformer Connections and Basics
· In a delta connected ( Dd ) group of transformers, the line voltage, V L is equal to the supply voltage, V L = V the current in each phase winding is given as: 1/√ 3 × I L of the line current, where I L is the line current. One disadvantage of delta connected three phase transformers is that each transformer must be wound for the fullline voltage, (in our example above 100V) and for ...
