The output end of the measurement assembly is directly connected with the input end of the measurement range automatic adjustment assembly. The input end of the analog quantity and digital quantity conversion assembly is directly connected with the output end of the measurement range automatic adjustment assembly, and the output end of the analog quantity and digital quantity conversion assembly is directly connected with the input end of the phase measurement calibration central processing unit assembly; the input end of the communication transmission display assembly is directly connected with theoutput end of the phase measurement calibration central processing unit assembly. The voltage and current phase measurement calibration equipment can realize calibration of voltage-to-voltage and current-to-current phases.

Description

technical field [0001] The invention relates to the technical field of power equipment calibration, in particular to a voltage and current phase measurement and calibration equipment. Background technique [0002] Since the beginning of the 21st century, with the rapid development of the power industry, in order to maintain the safety and stability of the power system, the calibration of power equipment has become more and more important, and the phase calibration of voltage and current has also attracted more and more attention. In the domestic phase calibration equipment industry, for a long time, only the phase calibration and adjustment of voltage to current between the same phase can be performed, and the phase adjustment of voltage to voltage and current to current phase between two phases cannot be performed. Therefore, the application prospect of the voltage-current phase measurement and calibration equipment that can adjust the voltage-to-voltage and current-to-curr...
