EU introduces new electrical standards

It was learned at the 9th EU Lighting Conference that EU member states have implemented new electrical technology standards since January 1, 2002. The European Union's unified standards group CENELEC proposed a new standard called EN61000-3-2:1995. Although European and American producers strongly oppose it, the European Commission has recently passed it and has been adopted by member states. This new technical standard will be revised on January 1, 2004. The main goal of the new technical standards is to ensure that the public distribution network is protected from low-frequency radiation. The specific measures are as follows: 1. The EU has set a mandatory upper limit for the low frequency emitted by telecommunications technology products and other electrical and electronic products. The amount of radiation is limited. 2. Specify the limits of the harmonic currents that are passed to the public power supply system and specify the harmonic components of the input current generated by the equipment. 3. The input current for electrical and electronic products must be greater than or equal to 16 amps per phase and can be connected to a low voltage distribution system. 4. Provide various technical detailed data and diagrams, such as measurement of harmonic current, measuring device, measuring program, etc. The first three are to protect the distribution network from interference, and the fourth is to provide data, diagrams, and limit harmonic currents. Limiting harmonic currents include: household products, tools (except portable power tools), dimmers for incandescent lamps, illuminating equipment (such as electric lights, equipment that does not include built-in illuminators for other purposes, such as photocopiers) With projectors, listening equipment, equipment with special wavelengths (specified in the standard).
