Probe impedance for plug discharge test | - Probe impedance探头阻抗 | WG2 | 2009 CTL Plenary Meeting |
插头放电测试探头阻抗 | - Plug discharge插头放电 | WG4 | 2009年CTL全体大会 |
- >= 100 MΩ ≥100 MΩ | |||
- 25 pF or less ≤25 pF | |||
Question问题 | |||
When the plug discharge test is performed using a voltage probe and oscilloscope for direct measurement of the voltage decay, what probe impedance shall be used to ensure uniform and comparable results? | |||
Note: IEC 60950-1/2005 specifies 100 MΩ ± 5 M Ω in parallel with an input capacitance of 20pF ± 5 pF. | |||
当使用电压探头和示波器直接测量插头残余电压时,应使用什么阻抗的探头确保一致的和可比较的结果? | |||
注:IEC 60950-1/2005规定100 MΩ±5 MΩ并联电容为20pF±5 pF。 | |||
Decision决议 | |||
If the relevant standard does not contain contradictory requirements, a voltage probe having an input impedance of 100 MΩ or greater in parallel with an input capacitance of 25 pF or less, shall be used for this test. | |||
For other (automatic) equipment with special measurement techniques equivalent measures shall be taken to ensure comparable results.如果相关标准不包含与本文件矛盾的要求,则试验应使用输入阻抗大于等于100 MΩ且输入电容小于等于25 pF的电压探头。 | |||
对于具有特殊测量技术的其他(自动)设备,应采取同等措施,以确保获得可比较的结果。 | |||
Explanatory notes注释 | |||
This issue was raised at the 2008 CTL meeting after discussing the proficiency testing program on plug discharge 2007/2008. Participants used several different probe impedances, which caused inconsistent results. | |||
这一问题是在讨论了2007/2008年插头残余电压能力验证方案之后,在2008年CTL会议上提出的。参与者使用了几个不同阻抗的探头,导致了不一致的测试结果。 |
