Product Feature And Application
1.One time wiring, can complete the direct resistance test, ratio test.
2.Direct resistance test function, for Yn-type, Y-type and △-type windings can be used for three-phase automatic testing, and calculate the three-phase imbalance rate; the highest output current of 20A, to meet the distribution network transformer low-voltage coil very low resistance value of the test.
3.Ratio test function, with three-phase, single-phase, Z-type transformer test function; PT / CT ratio, polarity test function; blind test function.
4.With a variety of wired, wireless communication interface, convenient instrument function expansion.
5.The instrument adopts embedded Linux operating system with high security, smoothness and ease of use.
6.The instrument adopts A7+M4 dual-core architecture, i.e., to meet the real-time measurement, but also meet the smoothness of operation.
7.Industrial-grade 7-inch large screen display, fresh and simple display style design, to create a comfortable and convenient human-computer interaction experience for you.
8.The instrument is powered by a large-capacity lithium battery with a built-in charger,which is convenient for users to charge at any time.
