IEC 61000-4-24-2015電磁兼容(EMC)--第4-24部分：試驗和測量技術(shù)--HEMP傳導(dǎo)騷擾的保護裝置試驗方法 基礎(chǔ)EMC出版物This part of IEC 61000 deals with methods for testing protective devices for HEMP conducted disturbance. It includes two-terminal elements, such as gas discharge tubes, varistors, and two-port SPDs, such as HEMP combination filters. It covers testing of voltage breakdown and voltage-limiting characteristics but also methods to measure the residual voltage and/or the residual current, peak rate of rise and root action for the case of very fast changes of voltage and current as a function of time. This standard does not cover insertion loss measurement methods.
