The order applies to the rated input current of 5A ~ 10kA, the accuracy of 0.02 to 2 grade, made of copper fittings and DC shunt resistor elements between the plate or rod composed of the initial verification, use and subsequent verification check. Also applies For measuring high-power direct current resistance test standard. 2. References This procedure refers to the following documents.

3 Overview

DC shunt to measure direct current four-terminal resistance measuring work. It consists of two copper connectors and between A plate or rod resistance components, the voltage drop across the shunt on the potential of the terminal mounted on the joint leads. Shunts The rated voltage drop at the standard value selection, such as 75mV. Shunt metrological parameters of the rated input current IN, Nominal output voltage UN and the nominal shunt resistor RN (RN = UN/IN), when applied to the input current shunt I1, this When the output voltage of the U2 (when the output current is zero), the actual definition of the shunt resistor is shown RM = U2/I1.

4 metering performance requirements

4.1 accuracy class 4.1.1 DC shunt accuracy level is divided into 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2 7 levels. Relative error is defined 4.1.2 DC shunt is. γ = U2-I1RNI1RN × 100% (1) 4.1.3 DC shunt relative error may also be equivalently expressed as. γ = RM-RNRN × 100% (2) Formula (1), the formula (2). γ --- shunt relative error; U2 --- shunt output voltage indication, mV; I1 --- shunt the input current indication, A; RN --- shunt resistor nominal value, mΩ; RM --- shunt resistor actual indication, mΩ. ......
