Research and Development of an Automatic Calibration Device for a Tester of Three-Phase Zinc Oxide Arresters
A multi-parameter three-phase zinc oxide surge arrester plays a crucial role in the power system,and its performance directly affects the safe operation of the power system,so it is of great significance to accurately test and calibrate multi-parameter three-phase zinc oxide surge arresters.However,traditional manual calibration methods have issues such as low efficiency and poor accuracy.In order to address these problems,this paper proposes an automatic calibration device for multi-parameter three-phase zinc oxide surge arresters based on digital vector signal synthesis and high-precision closed-loop feedback technology,so as to improve calibration accuracy and efficiency.
