Product Functions:

The TRW-310 Three-Phase Transformer DC Resistance Tester is a new-generation rapid testing device that integrates magnetization-assisted testing, three-phase testing (Yn, Y, △), and demagnetization functions. It is an ideal solution for measuring the DC resistance of large power transformers. The instrument features a high-resolution true-color LCD display and offers both touch and rotary knob operation for ease of use in the field. With Chinese menu prompts, it is simple and intuitive to operate, allowing for all DC resistance testing items to be completed with a single connection. The testing speed is fast, the accuracy is high, and it has a wide range.

Product Features:

1. Three-Phase Testing: Supports three-phase measurement for Yn, Y, and △ type windings, and calculates the three-phase unbalance rate.
2. Multi-Functionality: The test power supply has a maximum output current of 50A (optional for different models) and a testing range of 0-25kΩ, covering most transformer testing needs. It integrates both magnetization-assisted and demagnetization functions, meeting a variety of on-site testing requirements.
3. Assisting Judgment: Automatically calculates the rate of resistance change over 5s, 15s, and 30s during testing, assisting technicians in determining data stability and preventing misreading.
4. Large Memory Capacity: Equipped with a thermal printer and can store up to 200 data entries in the device, with support for USB storage for large volumes of data.
5. Convenient and Easy to Use: Features a 7-inch industrial-grade true-color display with a fresh, simple design. Fully touch-controlled with a single rotary knob for a comfortable and convenient user interface experience.
