GB/T 24337-2009
ActivePower quality - Interharmonics in public supply network
电能质量 公用电网间谐波
Application Summary AI generated
This standard specifies the allowable values, measurement methods, and assessment criteria for interharmonics (voltages or currents with frequencies that are not integer multiples of the fundamental frequency) in public low-voltage, medium-voltage, and high-voltage AC power supply networks. It is applied by power utilities, industrial facilities, and electrical equipment manufacturers to evaluate and limit interharmonic distortion caused by devices such as variable frequency drives, arc furnaces, and static converters. The standard ensures power quality compliance and mitigates risks like equipment overheating, flicker, and communication interference in the public grid.
