Transformers with K Factor

The K Factor is a norm that indicates the capacity which the transformer posseses to feed non lineal charges (for example: lights, electric motors, industrial charges, telecommunication and electric units) without exceeding the temperature of operation for which it is designed. Furthermore, the K factor is an indicator of the capacity that the transformer has to support the content of currents and harmonic tensions (fundamental components of the tension and current) while operating within the temperature that its isolation system is designed for. Our transformers comply with all of the updated norms and regulations, both internacional (ANCI & IEEE amongst others) and national, which deal with the K Factor as related to transformers. In the following table we can see a few applications and characteristics of the K Factor in different types of equipment.
