GB/T 17626.7-2008 Electromagnetic compatibility—Testing and measurement techniques—General guide on harmonics and interharmonics measurements and instrumentation,for power supply systems and equipment connected thereto
Abstract
This part of GB/T 17626 is applicable to measuring instruments that measure spectral components up to 9 kHz superimposed on the fundamental wave of a 50 Hz or 60 Hz power system. From a practical perspective, this part distinguishes between harmonics, interharmonics, and other components exceeding the harmonic range up to 9 kHz. This part defines measurement devices for testing equipment item by item according to the emission limits given in relevant standards (such as the harmonic current limits given in GB 17625.1); it also defines devices for measuring harmonic current and voltage in actual power supply systems. The measurement instruments used to measure beyond the harmonic frequency range up to 9 kHz are temporary provisions (see Appendix B).
