K-factor rating of a transformer is an index of its ability to supply harmonic content in its load current, while remaining in its operating temperature limit and its insulation class. It indicates that a given K-rated transformer can supply its rated KVA to load having specific amount of harmonic content.
Our Manufacturing Range: up to 5000 KVA, 11KV & 33 KV class
The substation is installed and mounted on skid frame or wheels or channels and is provided with lifting hooks. Enclosures are designed to provide protection against environmental elements and provide protection from outside contact.
A K-7 Rated transformer is rated for 50% linear and 50% non-linear. The overall function of the ULTRA K Isolation Transformer is to deliver conditioned power to a nonlinear high-harmonic current load and operate at safe temperatures while minimizing the harmonic current delivered to the power grid.
A K-Factor rated transformer is one which is used to deal with harmonic generating loads. Harmonics generate additional heat in the transformer and cause non-K-rated transformers to overheat possibly causing a fire, also reducing the life of the transformer. K-rated transformers are sized appropriately to handle this additional heat and tested to UL 1561 rigid standards for K-factor rated transformers. The way a K-rated transformer works is it uses a double sized neutral conductor and either change the geometry of their conductors or use multiple conductors for the coils.
