??InducTek Power Electronics ??provides high quality reactors and inductance for power factor correction system (PFC) and active power filter (APF) in electric energy quality field.

　　Electric energy quality means that in electric power system. The ideal energy power should be fine symmetrical sine wave. Certain factors would deviate sine wave and troubles of electric power quality occur . Problems electric power quality may be defined as : deviation of voltage , current or frequency which are unsuitable for use involving voltage fluctuation and saltation , unbalance of three –phase , instant or temporary over-voltage , wave distortion (harmonics) , voltage sudden increase and decrease or breaking off.

　　In modern electric power system, voltage sudden increase, decrease or breaking off and wave distortion (harmonics) have already become the most important problems of electric power quality.

　　Improvement measures:

　　(1) Improving power factor to keep reactive power in balance.

　　(2) Determining reasonable radius of power distribution.

　　(3) Selecting reasonable conductor area of power supply system.

　　(4) Selecting reasonable distribution equipment and avoid over loading.

　　(5) Adopting reasonable voltage regulation methods such as in stalling compensation devices in series, installing regulators for transformers, installing same term phase modulators or capacitors of static electricity.
