IEC 61000-3-2

IEC 61000-3-2 is an international standard that regulates the limits of harmonic currents emitted by electrical equipment. Harmonics are distortions in electrical signals that can cause inefficiencies and interference in power systems. This standard aims to ensure that devices, like computers and appliances, do not produce excessive harmonic currents, promoting better compatibility with the power grid and reducing negative impacts on other equipment. By adhering to this standard, manufacturers help enhance overall power quality and reduce the risk of electrical issues in homes and industries.
