Non-linear loads generate high levels of harmonic currents. When supplying power to these loads, a special transformer design is necessary.
Typical non-linear loads include desktop computers, AC variable speed drives, HID lighting, electronic ballasts, inverters and welders. Of these non-linear loads, the major source of harmonic currents is the switch mode power supply found in desktop computers, data processors and other office equipment.
MODERN non-linear load isolation transformers use special winding techniques to minimize eddy current losses generated by harmonic currents. A double-sized neutral conductor handles the excessive neutral current found in non-linear load applications.
The amount of harmonics produced by a given load is represented by the term K factor. The larger the K factor, the more harmonics are present. Linear loads have a K factor of 1; switch mode power supplies typically have a K factor as high as 20.
Modern non-linear load isolation transformers are shielded for cleaner power and carry the Acme exclusive 10-year limited warranty.
