Harmonic Distortion Level of Special loads and Method of Harmonic Distortion Management

Due to the development of electric energy conversion technology and need for energy saving most of the electric machinery and equipments are using power semiconductor switching elements, On the contrary semiconductor switching device is more sensitive to the voltage instability and voltage distortion. In order to manage the voltage distortion following foundation should be settled down in advance. First, reasonable and objective technical guidelines should be established. Second, monitoring network for power quality should be operated. In this paper measurement results of the harmonic distortion of the special loads are given and method for harmonic pollution management is discussed.
