泄漏电流测试仪:国内220V交流电的电器之泄漏电流是0.75MA,在家用电器中,泄漏电流是指运行的
电气部分与绝缘之后的金属间的安全电流。测试方法:家用电器在工作电压下工作时,将电器外壳与大
地绝缘,若将外壳与电器电极用一根导线连接,导线中会有电流流过,这个电流便是泄漏电流。泄漏电
流的存在表明了电器绝缘作用的有限性。因此,泄漏电流的大小是衡量电器绝缘程度好坏的指标之一,
也是家用电器安全的重要指标交流豪安表的一端接在电源上,去掉接地线后,把交流豪安表的另一端接
在金属间上即可。
simpson228 AC/DC泄漏电流表主要测试AC/DC泄漏电流,设计符合最新的UL、IEC60990和
ANSI标准。 simpson228查出当前AC和DC漏出并且模仿人的反应在三个不同水平 -- 反应,放弃,
以及灼伤危险。
每个Simpson228具有弹簧夹、指南和电池以及测试笔。
· 查出危险AC & DC 泄漏电流在电子或电子设备导电性表面
· 设计遇见新的IEC、ANSI和UL指南
· 反应,放弃和无重负的烧伤危险网络测量
· 电池操作为最大轻便
