ActiveElectromagnetic compatibility—General—Part 7: Power factor in single-phase systems under non-sinusoidal conditions
电磁兼容 综述 第7部分:非正弦条件下单相系统的功率因数
Application Summary AI generated
This standard provides methods for calculating and measuring power factor in single-phase electrical systems where voltage and current waveforms are distorted by harmonics. It is applied in electromagnetic compatibility (EMC) testing and product design for telecommunications equipment, household appliances, and other electronic devices operating under non-sinusoidal conditions. The standard ensures accurate power quality assessment and compliance with EMC requirements in environments with significant harmonic distortion.
