Fonctionnalité:
1. One connection is sufficient to perform both the direct resistance and variable ratio tests.
2. The direct resistance test function allows for three-phase automatic testing of Yn, Y, and △ windings, along with the calculation of the three-phase unbalance rate. The maximum output current is 20A, which is ideal for testing the very low resistance of low-voltage coils in distribution network transformers.
3. The variable ratio test function supports three-phase, single-phase, and Z-type transformer testing, as well as PT/CT variable ratio and polarity testing. It also includes a blind test function.
4. Equipped with various wired and wireless communication interfaces, the instrument allows for easy expansion of its functions.
5. The device runs on an embedded Linux operating system, ensuring high security, smooth operation, and user-friendly functionality.
6. The instrument utilizes a dual-core A7+M4 architecture, enabling real-time measurements and seamless performance.
7. The industrial-grade 7-inch display features a clean and simple design, offering a comfortable and user-friendly human-computer interaction experience.
8. This device is powered by a large-capacity lithium battery with a built-in charger.
