Problems solved by technology

[0003] First, there is no traceability chain within the naval system. Although each technical organization can organize the traceability to ensure the smooth progress of the verification work, it is difficult to guarantee the accurate and consistent technical support and scientific research guarantee conditions required by the equipment research institute;
[0004] Second, there is no equipment failure inspection and acceptance test capability, and the purchase and maintenance of high-precision electrical measurement standards are relatively expensive;
[0005] The third is that there is no scientific research support condition for special electrical measurement standards: in the development process of high-precision electrical special and on-site test standards, high-precision electrical measurement standards are required to provide technical conditions for scientific research experiments, assessments and tests. Technical capabilities for standard scientific research support, the way for local units to conduct electrical special measurement standard scientific research support
