Components for low-voltage surge protection—Part 352:Selection and application principles for telecommunications and signalling network surge isolation transformers(SITs)


Standard in brief
Scope of Application:  
本文件包含了电涌隔离变压器(SIT)的应用,适用于信号电压峰峰值不大于400 V的电信变压器。这类变压器在输入和输出绕组间有无屏蔽时都具有较高的额定冲击耐受电压。SIT作为电涌防护元件,用来抑制共模电涌向前传播。本文件介绍了SIT的选择、应用原则及相关信息。本文件不包含电力线路通信变压器的相关内容。
