what is tertiary winding in transformer?What is its purpose?
Answer Posted / prashanth kumar hg
Apart from the Primary & Secondary windings, there
sometimes placed a third winding in power transformers
called "Tertiary Winding".
Its purpose is to provide a cirulating path for the
harmonics (especially third harmonics) produced in the
tranfmormers along with power frequency (50Hz. third
harmonic means 150 Hz oscillations).

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
