Due to the existence of iron core reluctance, variable current transformer in the transfer process will produce errors, the basic error of various types of transformers is accomplished by transformer calibrator.

由于铁心磁阻的存在，互感器在传变电流的过程中就会产生误差，各种类型的互感器的基本误差是通过互感器校验仪完成的。 所以互感器校验仪是电力系统中不可或缺的重要设备。

A flow-separating calibrator was developed,which is mainly composed of three systems: XHV,UHV and flow separation. The ultimate pressure,10-10 Pa,was thus obtained in the XHV calibration chamber by combining the magnetically levitated turbomolecular pump with non-evaporable getter(NEG) pump.

分流法超高/极高真空校准装置由极高真空(XHV)系统、超高真空(UHV)系统、流量分流系统三部分组成。

Result of experiment indicates that all functions we expected for the calibrator have been achieved.

实验结果表明,所设计的智能化现场温度校准器的预期功能均得以实现,绝大部分指标也符合要求,部分性能未达到设计要求,这在文中给出了详细说明,并提出了改进建议。

Virtual instrument technology is applied to develop a virtual OECT calibrator.

采用虚拟仪器技术开发一套虚拟校验仪。
