Summary on Calibration Technology for Electronic Transformer
摘要
Abstract
According to relevant national standards,it is necessary to carry out calibration on electronic transformer before its operation in network and in its utilization,and calibration methods and technologies for electronic transformer become research hot points for many domestic scientific research institutes. Therefore,this paper respectively summarizes calibra-tion methods for digital output typed electronic transformer and analog output typed electronic transformer. It also analyzes key technologies influencing precision of verifying electronic transformer in aspects of selection for etalon,data acquisition, signal synchronization,calibration algorithm,and so on. It introduces newest developments of present electronic transform-er in field calibration,online calibration,optimized calibration algorithm,new typed calibration devices,and so on.关键词
