Winding Transformer By Pvj Power Solutions

We are engaged in manufacturing and supplying of Winding Transformer in Solan, Himachal Pradesh, India. In some high rating transformer, one winding in addition to its primary and secondary winding is used. This additional winding, apart from primary and secondary windings, is known as Tertiary winding of transformer. Because of this third winding, the transformer is called a 3, 4 or 5 winding transformer.
Tertiary winding is provided in electrical power transformer to meet one or more of the following requirements-
It reduces the unbalancing in the primary due to unbalancing in three phase load.
It redistributes the flow of fault current.
Sometime it is required to supply an auxiliary load in different voltage level in addition to its main secondary load. This secondary load can be taken from tertiary winding of three winding transformer.
As the tertiary winding is connected in delta formation in 3 winding transformer, it assists in limitation of fault current in the event of a short circuit from line to neutral.
