K-Rated Transformers

K-Rated Transformers

Capacity Range upto1000 KVA, 3 Ph

K-Rated Isolation Transformer is to deliver conditioned power to a nonlinear high harmonic current load and operate at safe temperatures while minimizing the harmonic currents

In a data centre, all the distributed power loads are connected through a non linear power source, due to which HARMONICS generation is unavoidable. These generated Harmonics are flow back and directly effects the main power source, which a UPS. The effect of harmonics de-rates the capacity of UPS. Hence 100% utilization of UPS capacity becomes wasted. The effect of harmonics also creates much heat in the transformers of UPS.

To eliminate these direct effects on UPS, K-Factor Transformers are designed based on the harmonics present the load. The special design of K-Factor Transformer helps us to depend on much to eliminate or withstanding from the
effects of Harmonics.
