  • what is tertiary winding in transformer?What is its purpose?

    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).

    In a primary-secondary-tertiary system (Figure 3), things start to get a bit more complicated, but the principles are all the same. The common pipe (whether it is between the primary loop and the secondary loop, or the secondary loop and the tertiary loop) acts as the decoupler, so flows act independently of one another and there is extra degree of thermal isolation.
