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 powersource, due to which HARMONICS generation is unavoidable. These generated Harmonics are flow back and directly effects the mains powersource, 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 Transformer 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.
