Transformer loss parameter Tester was developed by our company, developed specifically for transformer loss measurement of high precision instrument, for a variety of no-load loss of transformer, no load current, load losses and impedance parameters such as voltage can make precise measurements. The instrument has small volume, light weight, high accuracy, high stability, the advantages of simple operation and easy to learn, fully replacing the old method for transformer loss measurement method using tables, simple wiring, test, record, greatly improving efficiency. To large-screen color LCD display window, graphical menu operation and features a Chinese character prompt, set multiple parameters in one screen of display interface man-machine conversation interface, easy to use, fast, and is the preferred product for users at all levels.
