DC high current measurement process control
The accurate measurement of DC large current plays an important role in the production management of electrochemical and electrometallurgical industries. At ISO ,
In the IEC and China standards, there is no corresponding technical standard and measurement technology for DC high current measuring equipment.
specification. Since there is no uniform standard, the DC current in the electro-chemical and electro-metallurgical industry cannot be accurately and consistently measured.
The economic indicators related to DC power consumption are not comparable, and the technical conditions of electrolytic production processes cannot be optimized, thus reducing electricity.
The utilization rate and economic benefits seriously restrict the progress of production management technology.
Due to DC high current measuring equipment (including measurement standards and current measuring devices) only under laboratory conditions
Calibration does not guarantee that the measurement results under field conditions are consistent with the results measured in the laboratory. for
Solve the problem that the field DC large current value is not comparable with the laboratory value, according to GB/T 19022.2-
2000 Quality assurance requirements for measuring equipment - Part 2. Guide to measurement process control (idt ISO 10012-2.1997)
The measurement process concept, that is, the measurement as a complete process, from the scientific basis of the measurement and measurement
The traceability of the quasi-quantity and the start of calibration, as well as the determination of the maximum allowable error of the current measuring device,
The measurement confirmation, verification or adjustment, the objective data is presented, and the measurement standard and the measurement given by the current measuring device are finally confirmed.
The results meet the expected usage requirements, and at the same time confirm the DC high current magnitude to the laboratory DC
The flow ratio reference standard is traceable, and the magnitude of the current is comparable under different conditions. DC high current measurement
The process validation and process control are standardized and managed, so that the measurement quality of the current can be effectively controlled.
1 Scope
