But, what about the Harmonics they ( the CFLs) generate? In the process of improving upon the quantity of electricity that we cosume, are we not corrupting the “quality” of electricity?
It is “TERTIARY WINDING” and not “TERTIALY WINDING”. A majority of big power transformers, particularly, ICTs (inter-connecting Auto transformers) which are STAR-STAR connected, do have a Tertiary winding connected in Delta, to provide a path for the circulation of Zero Sequence Currents.
Alternately, in some transformers, tertiary winding can also be used to supply a minor load at a different voltage than the main secondary winding.
In yet other cases, thro the tertiary winding, a shunt reactor may also be connected for earthing or other purposes.
