| 中文摘要: |
| 冲击电流试验是评价计量仪表耐受瞬时大电流能力的重要型式试验项目之一,对评价仪表实际运行中的安全性能具有重要意义.针对电流探针和数字示波器试验装置等不确定度来源,提出一种校准冲击电流试验装置的方法,并结合实例详细地给出评定测量不确定度的过程,为冲击电流试验的校准工作提供参考经验. |
| 英文摘要: |
| Impulse current test is one of the important test items to evaluate the ability of measuring instrument to withstand instantaneous high current. It is of great significance for evaluating the safety performance of meter in practical operation. Aiming at the sources of uncertainty of current clamp and digital oscilloscope test equipment, a method of calibrating impulse current test equipment is put forward, and the process of evaluating uncertainty of measurement is given in detail with examples, which provides technical basis for the smooth development of impulse current test. |
