Answer / k.prakashchandra

You mean the secondary is delta and output is 3 phase 3
wire.Then to create neutral ,you have to connect the
terminals to 3 phase neutral forming inductor coils and use
the star point as neutral.The easiest way is to connect the
terminals to a 3phase auto-transformer of correct capacity
and use the star point for neutral

Answer / nimda

If the neutral is intended for single-phase to neutral full
load current then connect a 3-phase reactor with zig-zag
winding or a drive isolation transformer with Dyn winding of
suitable rating.

If the neutral is only for measurement by a meter with high
input impedance then 3 resistors connected as a star can be
used.
