I want Primary side delta and Sec side Star connection
transformer . but i have received Star - Star
transformer ,shall i use the same transformer by giving the
only 3 ph on Primary side without Neutral connection on the
Starpoint.
Answer Posted / dolphinopera
in transformers the
starting and finishing
end of the phase
windings are brought
out. hence you can
connect the windings
either in star or in
delta. another
important thing, if the
star winding is used
without neutral there
is a possiblity of
damage of winding.

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
can we use ZNyn11 transformer instead of Dyn11 transformer in distribution for effectively eliminating harmonics from the industrial loads.
