See figure12. 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 5.5 4.0 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℉) 5.2 Unless otherwise noted, all tests are to be conducted with appliance connected to a 120VAC, 60Hz power source. 除非另外注明, 否则所有样机都将连接在120V/60Hz电源下进行测试. 5.3 All equipment used must be calibrated on an annual basis. Calibration stickers with last calibration and calibration due date must be affixed to each instrument. 使用的所有设备都必须以一年的基准进行调校, 其调校日期和调校周期必须用黏纸黏固在每一个仪表上. 5.4 The leakage current is to be measured between the (dead-m
