Research on Accuracy of Secondary Signal of Electronic Voltage Transformer
Electronic voltage transformer plays an important role in intelligent distribution equipment,and the accuracy of the secondary signal of the electronic voltage transformer is the key to intelligent distribution equipment.The 10 kV resistance type electronic voltage transformer as the example,the simulation model is built.The simulation analysis on the influence of cable length on secondary signal accuracy of electronic voltage transformer is carried out.Then the electronic voltage transformer accuracy test environment is set up and the accuracy test under different lengths cable is completed.Through the simulation and test data analysis,the influence of cable length on the accuracy of secondary signal is obtained.The research results have practical significance for the reasonable selection of cable length and the improvement of accuracy.
