These transformers designed for high efficiency with low flux density and current density to reduce the losses and heat Primary 3wire system and output 4wire system with zig-zag winding to reduce the imbalance and non linearity.
And electro static shield are provided between input and output for high frequency /harmonics attenuation.
Where loads are nonlinear unbalanced the neutral current is generated the transformer, core and coil get over heated.
We have to employ a technique to reduce harmonics by adopting low flux density and current density with suitable shielding.
