K-13 Isolation Transformer Data Center

With the support of our expert, our company is dedicated Exporter, Manufacturer & Supplier of K-13 Isolation Transformer Data Center in Shenzhen, Guangdong, China. There are triple harmonic and other odd times harmonic in the power network and the user load. The zero-sequence third harmonic can cause increased neutral line current and other odd times harmonic additional heating in the winding. K-factor transformer is specially designed to withstand harmonic. According to the specifications of ANSI/IEEE C57.110-1986, K= a LH (PU) h. K-factor ranges from 1 to 50. 1 indicates a linear load(no harmonic) and 50 terribly harmonic environment. The larger the K-factor, the stronger the capacity of eliminating harmonic interference of the transformer.
