摘要
回路电阻测试仪能够提供大电流,并能有效地消除测试电流波动对测量结果的影响,因此广泛应用于电力系统开关设备接触电阻、导电回路电阻的测量中。文章阐述回路电阻测试仪的基本误差检定方法,并对其示值误差测量结果的不确定度进行评定。
The loop resistance testing instrument can provide high -current, eliminate the influence of measuring current fluctuation to measuring result, and has been widely applied in measure switchgear contact resistance and conductive circuit resistance of power system. The paper expounds the basic error＇ s verification method of loop resistance testing instrument and makes evaluation on indicating error＇ s measuring result uncertainty.
