Product Overview DK-45K1 on-site transformer calibrator is based on ARM+DSP large-scale electronic circuit and JJG169-1993JJG313-94JJG314-94JJG1021-2007, combined with advanced concepts of modern transformer test. It solves the problems of traditional transformer calibrator such as slow reactionlow automated process and complex operation. The device is reliable and fully functional. Main Features (1) Be able to test voltage transformercurrent transformerimpedance and admittance, easy to field test. (2) High-power lithium battery as power supply, easy to field test. (3) Use 640*480 high-resolution LCD to display. Humanized operation interface and design, touch screen aided, much more convenient. (4) Intelligent judgments of external line status. Tips of wiring errorvariable ratio and wrong polarity. (5) Test data changed into integers automatically and determine whether it's out of tolerance. (6) Get the field check result directly, pass or fail. (7) The device focuses on the technology which includes JJG1021-2007 procedure in Appendix D called voltage transformer load extrapolation error curve. (8) Mass memory can save the field check data for more than 1000 items. (9) Plastic mold case can anti-shock and pressure to protect the site operators and the equipments. (10) Advanced computer software for data management.
