The zone concept : design of low-voltage installations considering the spread of high frequency harmonics
The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy....

The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy. Electrical equipment and the use of electricity develops towards more energy-efficient and high-technology products, This implies at the same time that the power quality is impacted as well. The accelerated use of power electronics, harmonics (LF harmonics, up to about 2 kHz) became an important subject for both engineers and researchers. This included origin, impact and propagation of harmonics. The existing situation is that HF harmonics (above 2 kHz) are taking over the role of LF harmonics as an area of concern in the power system as well as for end-user equipment. The driving forces behind the increasing levels of HF harmonics are the increased introduction of energy-efficient and high-technology products and, ironically enough, the limitation of LF harmonics among others using active converters. The research group at Luleå University of Technology, to which the author of this thesis belongs, is one of the few groups in the world that has studied different aspects of HF harmonics.
