High-speed transformer verification device is a new generation of transformer verification device developed by our company. The design idea of virtual instrument is adopted. The user only needs to operate the virtual instrument interface on the computer screen through the mouse and keyboard to input the transformer type range accuracy level capacity power factor and other parameters can complete automatic testing of current transformers and voltage transformers as well as analysis calculation and database management of test results and can be printed according to user needs various records and certificates. 1. The automatic mutual-inductor calibration platform adopts a single chip microcomputer to realize the functions of measurement control and display. 2. With computer interface improve the level of office automation and reduce the labor intensity. 3. Can have a large screen display provide a friendly operation interface and rich measurement information. 4. It can automatically realize the measurement of the transformer and can automatically switch the current and voltage load box. 5. Possess good catching measures and be able to promptly inform users of wrong information. 6. This automatic transformer calibration station can reach level 2. 7. The transformation ratio of the standard transformer and the tested transformer does not have to be equal as long as the rated primary voltage or rated primary current of the standard transformer is greater than or equal to the rated value of the tested transformer it can be directly verified which is more convenient to use.
