Comparison of standards limiting harmonic distortion in power systems
Harmonic distortion in power systems is growing due to the popularity of switch-mode power electronic equipment. This electronic equipment has recognized advantages, including reducing weight and improving control and efficiency in power converters and supplies. A disadvantage of switch-mode power electronic equipment is that the low-cost utility interface design approach may burden the power system with harmonic loading. Methods to reduce this distortion exist but economic incentives do not. Standards are emerging as the most effective means to influence equipment design and control distortion in power systems. This work compares the major European and American harmonic limiting standards.<<ETX>>
