摘要:
为分析功率吸收钳法和线注入法电缆屏蔽效能测试方法的可比较性,进行了2种测试方法测试结果关系的推导与分析.介绍了功率吸收钳法和线注入法电缆屏蔽性能测试的原理,推导了表征电缆屏蔽性能的屏蔽衰减与转移阻抗两参数间的关系,利用该关系进行功率吸收钳法和线注入法电缆屏蔽性能测试数据比较分析,结果表明:截止频率以下,由于线注入法受试电缆为电短,屏蔽衰减与电缆长度相关,2种测试方法测试结果不一致; 截止频率以上,线注入法与功率吸收钳法受试电缆均为电长,测试结果一致.功率吸收钳法和线注入法测试结果相互关联,2种测试方法具有可比较性.
Abstract:
To analyze the comparability between absorbing clamp method and line injection method, the relation of the test results of two methods is derived and analyzed. The principles of absorbing clamp method and line injection method are introduced. The relation of shielding attenuation and transfer impedance which characterizes cable shielding performance is derived. The test results of absorbing clamp method and line injection method are comparatively analyzed by using that relation. It is shown that the test results of two methods disaccord with each other below cutoff frequency because of electric short cable in line injection method, however, the results agree with each other above cutoff frequency. The results of absorbing clamp method correlate to that of line injection method, and two methods are comparable.
