The value traceability of the calibrator's transient calibration performance parameters has realized the calibration function of the DC transformer transient calibrator.

Description

technical field [0001] The application relates to the field of intelligent equipment calibration, in particular to a calibration device for a DC transformer transient calibrator. Background technique [0002] As an important primary equipment for the construction and operation of the DC transmission system, the DC transformer provides accurate and reliable measurement information for the control, protection and stable operation of the system. Its operational reliability and measurement accuracy are directly related to the safe and stable operation of the DC transmission system. The DC transmission system requires faster sampling speed and wider frequency bandwidth for the control and protection signals, especially in the flexible DC transmission system. In the flexible DC transmission system, in order to improve the response speed of the flexible DC system and suppress the fault current, Improving the safety and stability of the power system puts forward higher requirements ...
