Many distribution systems these days have a high harmonic content on them attributed to all of the electronic and solid state equipment needed to operate business and facilities. Equipment such as PC’s, printers, copiers, faxes and solid state lighting control all cause a current to flow back in the neutral which traditionally did not carry and current.
K-Factor is a measurement of how high the harmonic content is in a building. Obviously the more floors and office the more equipment is needed to run the business and consequently has a high K-Factory. Dongan’s K-Factor transformers will provide years of trouble free service to large office buildings, industrial plants, processing equipment and any load with a designated harmonic content.
Dongan offers transformers rated K4, K13 and K20 but also offer high K factor.
