HZC-20A Transformer DC Resistance Tester
Features
1. The test power supply has a maximum output current of 20A and a test range of 0~25kΩ, meeting the testing needs of most transformers.
2. The instrument can automatically calculate the resistance value change rate within 5S, 15S, and 30S during the testing process, assisting test personnel in judging the stability of the test data and preventing misreading.
3. The instrument has multiple protection functions, including reverse electromotive force protection, open circuit protection, and power-off protection.
4. The instrument is equipped with a thermal printer, storing 200 data points internally and supporting massive storage via USB flash drive.
5. The instrument features a 7-inch industrial-grade true-color LCD display with a clean and minimalist design, full touch and one-button flywheel operation, providing a comfortable and convenient human-machine interaction experience.
Overview
For power systems, transformers are core equipment, and their long-term and reliable operation is crucial for the stability and reliability of the entire system. The DC resistance of transformers is a mandatory test item for semi-finished and finished products, installation, handover tests, and preventive tests by power departments. It can effectively detect manufacturing defects such as material selection, welding, loose connections, missing strands, and breaks in the windings, as well as potential hazards after operation. To meet the need for rapid DC resistance measurement, our company has developed a transformer DC resistance tester using its technical advantages. The instrument features a true-color high-resolution LCD screen with touch and flywheel knob operation, making it convenient for field use. It has a Chinese menu prompt function, making operation simple and intuitive, with fast testing speed, high accuracy, and wide range.
