See figure1&2. 泄漏电流 --- 从不带电金属零部件/马达壳表面和地线之间测得的电流.3.0 Reference Documents/参考文献:U.L.1017 CAN/CSA-C22.2 NO.243-01, dated 12-7-2001,CL 5.54.0 Equipment/设备:4.1 Frequency converter. (变频电源)4.2 Leakage current tester(泄漏测试仪)4.3 Stop watch(秒表)4.4 Leakage test switching box (made per the circuit shown in Figure 2) 泄漏测试盒(按图 2 原理制作)5.0 General Instructions/说明:5.1 Tests may be conducted at any ambient temperature within a range of 10-40 (50-100).℃℉测试可在 10-40(50-100)℃℉ 之内的环境温度下进行.5.2 Unless otherwise noted, all tests are to be conducted with...
