DJF-124 - Partial Discharge Detector
High-voltage Insulation Test Equipment
Model:DJF-124 Partial Discharge Detector
Application:
The partial discharge detector adopts a 10.1-inch touchscreen to replace the traditional operation method of oscilloscope tubes and physical knobs, making it more functional, user-friendly, and reliable in performance.
Features:
The partial discharge detector adopts a 10.1-inch touchscreen to replace the traditional operation method of oscilloscope tubes and physical knobs, making it more functional, user-friendly, and reliable in performance.
This instrument utilizes a 32-bit high-performance single-chip microcomputer circuit combined with touchscreen operation, not only extending its operational lifespan but also offering the following features: one-click automatic calibration, adjustable voltage divider ratio for high-voltage test voltage, and serial communication for test data upload. The device boasts high detection sensitivity, a wide range of applicable test objects, a large dynamic range for the amplification system, multiple frequency band combinations (nine types), and strong anti-interference capabilities.
When used in conjunction with a calibration pulse generator and input unit, this instrument serves as a practical partial discharge testing device widely employed by power departments, manufacturers, research institutes, and other organizations.
