ActiveElectromagnetic compatibility—Limits—Assessment of emission limits for the connection of unbalanced installations to MV, HV and EHV power systems
电磁兼容 限值 接入中压、高压、超高压电力系统的不平衡设施发射限值的评估
Application Summary AI generated
This standard provides a technical framework for evaluating the emission limits of unbalanced electrical installations connected to medium-voltage (MV), high-voltage (HV), and extra-high-voltage (EHV) power systems. It is applied by power utilities and industrial engineers to assess and limit harmonic and voltage imbalance emissions from large, single-phase or asymmetrical loads, ensuring electromagnetic compatibility with the grid. The standard is particularly relevant for planning and connecting facilities like electric arc furnaces, railway traction systems, or renewable energy plants to high-voltage transmission networks.
