$ ^! H @9 w, R, ^EQUIPMENT or PLUGGABLE EQUIPMENT TYPE B, that has a PROTECTIVE EARTHING CONDUCTOR, that the TOUCH CURRENT will exceed 3,5 mA r.m.s., but that the PROTECTIVE CONDUCTOR CURRENT will not exceed 5 % of input current, the tests of 5.1.5, 5.1.6 and 5.1.7 are not made.1 A! h, b. K7 X+ D$ A# C8 f7 \5 W, x! i
- Y$ h- I7 p! H9 r
该怎么分析接触电流有效值会超过3.5mA ,但保护电流不会超过输入电流的5% 呢?谢谢! |
