This digital partial discharge detector adopts LCD display instead of traditional oscilloscope tubes. It features high sensitivity, multiple frequency bands and phase window functions, enabling accurate and reliable partial discharge analysis for diverse power equipment.

• Digital LCD display replaces oscilloscope tube, with longer service life and clearer waveform presentation
• Multiple display modes: ellipse, straight line and sine wave, adaptable to different test scenarios
• Digital windowing technology (15°~150° adjustable) eliminates interference for precise measurement
• Supports single/double phase window selection and 150° ellipse rotation for flexible analysis
• Freezes and saves discharge waveforms for traceability and static observation of pulses
• 13 input units cover 6pF~250μF test sample capacitance range, with high sensitivity
• Three signal input channels (A/B/C) for multi-point simultaneous detection
